I have to say bro, there are alot of guys out there...but you know your stuff. You deserve way more recognition. Keep up the good work.

I really appreciate how you solve the problem by working through one item at a time. Just like my Dad taught me! Great job.

I admire your work ethic to make sure you're not wasting time. You went thru all the steps to make sure it was the fuel pump first instead of just throwing parts at it

I applaud your patience and though instruction. You are a most vital resource in educating our next generation of repair enthusious.. Thank you for restoring my faith in online KZfaq turorials

Was about to give up on my CRX with all its intermittent fuel issues. Thank you so much for this!!! 🙏

Just picked up a 91 sedan that is not getting fuel. Going to start down this path. I’m so glad you laid it out in a logical process. Crossing my fingers that it’s the relay and not the pump 😂.

I can confirm what he says at 16:20 is correct, don’t use that small sock that comes with the fuel pump, you’ll have issues like hesitation, bad idle, engine dies at 1/4 - 1/2 tank. Replace that sock with a longer OE style sock and save yourself the stress.

Experience is king

Mad scientist strikes again good work Jon great video

Great flipping video brother I just learned A LOT OF GOOD INFORMATION!!!!!! THANKS!!!!

Fuel pump went out on me half way through a seven hour drive. Long day... your video helped me troubleshoot it though, thank you.

As always quality vids! Thank you

Dude your videos are great quality.

Very informative. Keep up the good work!

I appreciate this info, I’ve been chasing around a stuttering/ bogging issue for a while since I’ve replaced the fuel pump with a whole unit, (different style sock) and my car dies at 1/4 tank

Wow very informative! best content I have seen in awhile! I watch plenty of repairs on different vehicles but, Never seen a video so informative and straight to the point. definitely subscribing and don't know why this is the first time for me seeing your work. highly impressed!

I appreciate the good information Now I know the 97 Civic trying to buy is gonna be an easy fix

You sound like a low-key ChrisFix. Great video! Thanks!

Very nice video man 👍👍👍

I put a smaller sock with my performance pump and it works fine but it's good to know how it's suppost to go on

Excellent vid man!👌

Thanks for helping us👍

excellent video !!

Glad I watched this. I just bought a 1990 Civic STD and it's a little boggy sometimes while driving and if I bring the rpms up while sitting still it kinda fluctuates and sounds like it's struggling. I know what I'm doing Saturday...

Amazing video, really all your content has been a game changer. I’m new to the world of car enthusiasts and just got an 88 ED hatch and your videos have already helped me a ton! Out of curiosity- do you have recommendations for which fuel pump works best for a 4th gen civic?? 🙏🏽💯👍🏽

Hey great info on civic I'm having trouble getting a 99 to start got spark any tips to check fuel pressure at the rail

thank you so much, my 90 sedan went through 2 pumps within a week because i had the wrong sock on it and couldnt figure out why. I guess now its time to pull the tank back out

I just replaced my fuel pump and followed your other video showing us how to and now new pump is not priming and check engine light will not turn off cranks but won't start,I am getting voltage just not sure how much also got a new main relay

Hey Jon, when you go to read the vacuum line off pressure, it's usually a good idea to pinch off the end of the disconnected hose so you're only reading the difference from the fuel pressure regulator and so your idle isn't effected too much by the vacuum leak.

Always great seeing your videos buddy. You are sharp my friend!! How did you gain your knowledge? I had someone do a head gasket on my 91 Si Tahitian Green, getting it back on the road. It was awesome the last few days. The shop also changed the fuel pump and relay so I thought I would be ok. Took it out to go to some body shops as my car needs a driver's side passenger. I pulled into the garage and parked. I decided I wanted to move the car and put the key in the ignition. All the lights went on but it would not turn over. Back to the drawing board buddy! Ugh!

good evening Sir, I have 1989 honda civic lx sedan 1.5 engine with dual points injection, I replaced my distributor, replaced both injectors primary and secondary, replaced sparkplug, cables, fuel filter, delphi fuel pump with the right sock, main fuel pump relay, the car runs good but suddenly spotting or skipping plus loose it power, specially when you are at light, the engine pistons compression is at 140 pounds are the cylinder, I need help figure out what is happening with my car. thank you for your great videos

The new aftermarket relay i bought was junk. I bought a fuel pressure gauge. It mounts above the filter. I think i bought the adapter from glow shift.Mini gauge was from summit.

You see when someone worked on a car before and notice the street hurry to patch and go style, 😎I'm learning, I changed a lot of things in my Son's 1992 civic" I called him today to finally tell him that it might be the Gas pump and filter,He bought another vehicle to then sell the civic very cheap,,like giving it away, but I took it home , It is a nice looking civic,,And watching your video, Im sure that is the problem.

Just wanted to share my experience with the fuel pump relay on my 90 civic. It would start just fine and I would drive to the gas station. After filling up it would not start, no fuel pump sound. I would wait a few minutes, turn the key and it would fire right up. Inside the relay are two separate relays, each with its own plastic cover. When the relay got warm, one of those covers would warp, preventing the relay from closing!!! I removed the plastic cover and haven't had a problem since.

Thanks for the inf my friend also my car dies yesterday check main relay and smell bad I change it and the car dozens start the check power to the black and yellow wire no power take the fp out test it direct to batt and run super fast the n car dozen crank no more the green ligh key show out one's in a while I really don't now what else to do I swap ecu and still the same problem do u have any suggestions for me I will appreciate this its crazy issue

I'm having issues with my car now haha Just changed the battery and now after an humid day it won't start... It's freshly built too!! Imma check it up when it gets hotter.

Hey bro I got a 90 integra it turns on but bogs and has a solids check engine light on .also doesn’t pass 3k rpms

Seeking Help for 91 CRX Si: I installed a new OEM main relay thinking it would get my car to start up. But, it didn't. When the car is in the ON position (under normal operation), I can hear the main relay click, followed by a secondary click that primes the fuel pump. Right now I am only getting the first click as the CEL goes off, and no secondary click, with no noise coming from the fuel pump. Apparently the fuel pump is not engaging. I was able to test & verify that voltage is being delivered to the fuel pump. Someone told me it could be a grounding issue, so I checked the ground wire connected to the thermostat housing, which was securely connected. Any idea if a bad ignition switch could have a direct correlation to the fuel pump not activating? Or is a bad ignition switch and a bad fuel pump two separate issues that may co-exist without being directly related to each other? I do have a Honda Service Manual, which is helpful, but because of my limited experience, I am not able to adequately understand the aspects of diagnosing electrical fuel delivery issues. I have followed the service manual test step to determine if there is voltage (10V) available when I connect the multimeter's positive probe to the BLU/WHT wire and the negative probe to the BLK wire of the main relay harness connector, then turn the ignition switch to the START position. I am not getting the 10V that the service manual says I should get, but only getting 0.03V. Does this mean the ignition switch could be bad? The engine does crank, it just doesn't start. I hope the information I have provided is enough for someone who can respond with a possible solution. I am basically trying to find out the following: 1. Do I have a bad fuel pump only? 2. Do I have a bad fuel pump AND a bad ignition switch? 3. Are the above two issues directly related, or are separate issues that don't necessarily correlate? Any amount of information & knowledge passed along would be greatly appreciated. Thanks.

Hi Jon, thank you so much for these videos - they're super helpful! Can you let me know the exact make and model fuel pump that you put in? Have you liked the performance from them?

What's the max amount of tq can those motors handle with stock everything?

Hi, great videos you have, very detailed and easy to follow. I’m trying to bring my ‘90 CRXsi back alive after sitting for years. After replacing all fluids, filters, dumping the old gas and putting a fresh gallon in, the car cranks but does not ignite. After a little debugging, I find the Alternator Solenoid fuse blows when turning the ignition to on. If I pull the plug to the fuel pump, it doesn’t blow. Also, the plug shows +12 volts when not connected. Pretty sure it’s the fuel pump, but trying to confirm if it is bad before doing the change. Also would replacing the pump assembly be advice or just the pump/strainer.

I had to watch the second part of the red hatch mistory. I will be honest. I haven't watched it yet but I was thinking fuel pressure. I'll watch it now and see if my guess was right from part one...

Love it

hey great video, maybe its the same for d16a9 motor? im having little issues to start the engine and when running, some irregular acceleration

THANKS!!!!!! :)

I have to replace the fuel pump on my 90 EF HATCH but the whole process of dropping the gas tank makes me feel like I can't do it, or atleast not by myself. My gas tank consistently shows around a half tank but then acts like it's completely out of gas and I've had this issue for a year. The fuel pump recently started whining the other day when I got up to about 90 miles per hour on the freeway ever since I've been babying it and it doesn't wind anymore but I know the fuel pump needs to be replaced.

My 95 honda civic does the one click with the CEL coming on once then turns off but it only clicks once does this mean that the main fuel relay is bad. Someone PLZ confirm ! Im going crazy !!! My civic is a d15b7, 5MT,

Good video

Having issues with my 89 civic will check filter and pump

my crx had this same issue thats crazy

Good video man. Id suggest getting a Harbor freight tester they are only $20 and mine always worked good.

Do you have any videos for 88 honda civic dx hatchback ? Or is the crx basically same ? Because Mine isn't starting anymore 😕

Wouldn't you want to test the fuel pressure at the end of the fuel rail? That would eliminate all possibilities of a clogged or faulty rail and injector o-ring failure?

Thanks for the tips trying to fix my car. What wheels are those on your track car?

I need help the carborator drowns with gas, what can i do?

What could be the symptoms of the fuel pump strainer falling off? I replaced my fuel pump and once i put everything back together i saw that crush washer thing that holds it on. I didn't know what it went to until now lol

Who made the carbon fiber gauge cluster trim? I made a handful of them for the 90-91 back in the day, (Ten By Ten Custom Carbon) but never saw anyone else producing that part. Looks good!

hi,GBH I have a problem similar with with this 90' honda on my 91' lx and will be going for a new fuel pump would you happen to remember the brand you bought or a brand you recommend to replace the old existing pump,and also are you any other social med. sites

Thanks for this video! I checked my fuel pump pressure and it read at around 28 psi. Disconnecting the regulator hose and the psi went to 38 psi. Would this be the reason for stumbling during acceleration in my 90 civic ex with only 90xxx miles?

I'm having the same problem with bogging down at more than 50 percent throttle. My motor is a d15b2 dpfi. I plan on doing a d16z6 swap but I'm just trying to get my current motor to run right first so that I can drive the car and move it if need be. I pulled my O2 and it was white. Will try a fuel filter and pump replacement since the z6 will need them anyways. My relay seems fine and my pump primes, but I haven't tested the voltage yet.

When you pulled the fuel pump , it’s missing the rubber insert that sits under the pump and above the fuel pump bracket , the orientation is correct as that’s only way it can go on there is a simple that strainer aka the sock sits in .

hey, brilliant video, my civic b16a1, have been stoped for 15 years, and cant make the engine run (yet), can i measure the fuel pressure without having the car running?

Im having the samw problem it boggs like it feels like its not getting any gas ive replaced injectors fuel filter wires and plugs could it be my fuel pump?

So I was looking up the location of the pcv for my car nd this video popped up. Maybe u could help me. I have a 89 civic hatchback dx with a d15b2 motor. Tryna smog my car but it wont pass. It runs rich at 15 mph but it passes at 25 mph. Already changes the coolant sensor nd thermostat but that didnt seem to work. Now my friend is thinking it could be the pcv valve

I just did this

I b swapped my ef with a conversion harness from mono tech. I was teaching someone to drive manual and they stalled. It wouldn’t turn on until after 2-4 key turns and giving it a bit of gas. Code 16 came up then went into limp mode, I turned it off then back on and the code was gone. It’s happened a few times. Mostly when running hot but never becomes a constant issue where I can’t drive the car. It always “goes back to normal”

So I bought a 1990 EF hatch and the gas guage doesn't work and it starts sometimes runs smooth and stuff but randomly starts any help the car randomly starts

I have a ef 91 with a b20b car sometimes cranks sometimes doesnt but i hear the fuel pump sound when turning key

Help... I just put an Ultra Street intake mani but it stumbles horrible on low rpm's after a hard pull... Some say bad injectors, others say I need bigger injectors... what fuel pressure should I have? My pump is a 255 Walbro

Hey Jon do you know what hood fits into a 90 Civic hatchback, I want to replace the hood and bumper filler, I'll appreciate your help

Do you have to soldier all fuel pumps? When you replace them because I don't know how to soldier. Is there a fuel pump I can buy that I don't have to soldier plug in?

My crx ECU fuse blows as soon as i turn the key to the ON position. i tried 2 ecu's and 2 diff main relays, blew a lot of 15a ecu fuses in the process, can't find out whats wrong...

The voltage drop from the battery to the fuel pump was a lot more than I expected. I was reading that the main relay in some older Hondas can add significant resistance to the circuit.

Just got a tube up on my 86 prelude so I changed the fuel filter cuz it was hesitating till it hit 2 k well it say fir a while and the battery went dead and it won’t start I spay starting fluid it runs a d I hear a clicking in the dash where the relay is located so it may or may not still be working but the fuel pump still not working

I changed fuel pump with new, replaced the relay under dash, replaced fuel filter and still am having it die intermittently and then not starting after. Relay clicks and fuel pump hums. Any ideas?

Are those Bbs RZ wheels, did you have to bore wheels to fit hub?

Did we ever figure out why this car was bogging out im having the same issue my distributor and fuel filter are new and I have a check engine light. I'm throwing a code 1 code 17 and a code 20

I put a new fuel pump not too long ago and it still does the same thing as you're describing where you give it gas and it kind of boggles and it doesn't turn off or stop it just you let go of the gas and then you push it again and it's back to normal what do you think it is do I need to put another fuel pump on there maybe the one I bought is defective

If you run around all the time on an empty tank your fuel pump will be running hot and most likely will fail sooner. I try and run at least a 1/4 tank of fuel to help cool the pump.

Hey bud, what would be a good fuel pump to run on my 88 dx b16a swap. My fuel pump went bad

You should make a video on reading ecu codes. I can't seem to find out what my ecu is throwing. Won't Rev passed 4k.

I having issues with my fuel pump not priming it was and now it doesn’t and I change the main relay for a new one and it worked and agin it stop priming ?

1:10 - The Left Front tire is on backwards. It's a directional tire, you're not supposed to cross-rotate them.

Hey man, great video!👍 I don't suppose you know the name of the wheels?

would you happen to know where to get the strainer or if there is a copy in another brand? i cant find the airtex fs121

Is there a way to test the fuel pressure with the car cranking but not starting?

I have same problem i change the sparkplug, htw, fuel filter, fuel pump and still sputtering when i rev it stalled and loss power but when i reverse it wont sputter or misfire it runs smooth but when i get to 1st to 2nd gear it sputtering

I replace my fuel pump now when i turn on the ignition position the fuel pump sounds harder & works fine but under the car you can smell a lil of gasoline but cant see any leack

Bro sounds like he related to Chris Fix lol

How much should it be at when you put it on the first key before turning it on ?

Hi there, I have 89 Civic Ef. My problem is when the fuel tank is full, it run fine. But, when fuel inside the tank drop almost empty( about quarter ) it doest run.. It's like no fuel pump into the engine. I bring it to a mechanic, even they can't solve the problem. Any suggestions.? Tq.

Hey Man, got a quick question I can't find an answer to. I Have a 92 prelude, It's been sitting for 7 years and has over a half tank, engines out, is there a way to make the fuel pump continuously run without the car running? I want to pump it out with the fuel pump like you can do with a Mazda diagnostic port and a paper clip. Getting a fuel pump pig tail and make it run off a battery is the only way I've found so far.

hey man, i'm trying to check my Injectors right now, and am i'm wondering if i need to depressurize the fuel sytem prior?

Going trough this now with my y49 she hesitates on acceleration and when I took the vac line off the regulator it didn't even spike just like a line lol but will that pump and sock work for a crx aswell

I have same problem on my 1990 Ef I replaced pump and fpr but still have same problem... stumbling on acceleration past 50% throttle.. ecu bad maybe ? Or injectors on dual point system . Fuel pressure read at 44psi with fpr vacuum line detached any thoughts ??

Does it matter how much LPH the new fuel pump has? Like mine is fucked up i guess on my 99 integra type r. Which do you recommend? And whats the minimum LPH?

Been trying to fix a P0172 code in my 2006 Honda Accord for some time now. Very frustrating.

Would u have any idea why my 1989 Civic Dx is only getting 120 miles per full tank? Already changed the fuel filter and air filter. 😭😭

Aye it's that one guy

Need help my car stalls when it’s about reach normal temperature. I changed fuel filter , changed spark plug, changed fuel pump relay, when I switch on I hear fuel pump prime, clean the injectors, adjusted the valves, when the car stalls after 20 seconds I start it it’s fine then stalls again after few minuites. I’ll be checking fuel pressure soon. I’ll keep you update on that also I ordered new ignition coil I’ll also update you on that. The compression are all good .
