Thank you, simple, quick and easy to watch. I'm going to check these groups next! Keep up the vids!

Really good video. I like how you touched the items you spoke of instead of making people guess. Top notch video. Thanks for putting your smarts to helping people !

Thanks for the video! It helped me to fix my truck! Both of my gnd wires were an issue!

Replaced all the grounds on my 1989 Chevy K2500. Added a few more. Made a huge difference all around. All the lights are about 50% brighter and everything seems to run better. Great video. Thanks.

Just want to say I owe you a case of beer! My truck was running fine and just wouldn't start one day. There was no gas to the TBI injectors. Changed fuel filter still no gas. Cleaned grounds you show in your video, IT STARTED RIGHT UP. Thank you again and if you want just send me a message. GREAT HELP and THANK YOU FOR SHARING!

Best information that saw on KZfaq thank you sir .

Great job on the video, you gave me some ideas to work on.

Thanks for showing that grond wire i did a carburetor from tbi swap and didn't connect my ground yet so I couldn't find my fuel pump wire good viedo

That tan and black wire cross ground was my problem too. Thank you so much! 🤘

Really appreciate this i have a 88 k1500 5 speed 350 short bed regular cab that my grandparents bought new and i have now owned it for 12 years its my baby and i keep it as clean and nice as i can it just now going on 120000 miles. Me and my wife wer headed back from jay Oklahoma with a trailer on and it just died. Everything stayed on (guages radio lights and so on) but it was basically like i pulled the coil wire off thats how it died. No spitting and sputtering. It had blown a fuse I believe it was a 15 amp fuse that said ecu and I believe thats the module that has the “prime wire” to kick the fuel pump on before the engine has started. Put another fuse in it turned key on it started and died popped another fuse. Then put another fuse in it and as soon as i would turn key on the fuse would pop. So with basically having no other options i put a 30 amp fuse in it and it didnt pop (i know it was stupid but was in the middle of nowhere and about a hour and a half away from home. I was hot and flustered. That worked got it home then put a 15 amp back in it and it didnt pop and hasn’t popped for the past 3 weeks then on my way home from work tonight was going down the road and it did the exact same thing everything stayed on but was like i pulled coil wire so i pushed in the clutch went into neutral and was gonna coast it till it stopped but before the engine quit rotating it busted back off and now has me really scratching my head. Obviously the fuse wasnt popped that time. The fuel pump is original to the truck none of the wiring in or on the truck is hacked up or anything so ima check all the grounds you pointed out. Im a hardcore gearhead just the darn thing got me flustered just because of whos it was and it means the world to me but you have givin me a little more to check out so i sure hope i can find something or i warned it that it was going to become carbureted lol sorry for the rambling and thank you wish me luck

Watched you video and instantly found my problem

thanks. grounds fixed the issue

i did a motor swap in my truck i put a 71' 350, and my fuel puel wont cut on at all, i hope this will help out

Howdy, Thanks for the video very informative. Question, please. (Vehicle 1993 Flair motor home 454 TBI) My symptom is: Starts for a few seconds and then dies. If I give it the gas pedal, let off speeds ups, then it dies. Keep feathering gas pedal stay lit, won't go high RPMs. But will keep running, if I keep feathering and letting off the gas pedal. Turn key on start, starts a few seconds dies. If give it gas to accelerate in park it dies. I can do the gas pedal thing give it gas let off, give it gas let off, and will stay lit, RPMs go up, as I stop doing this it dies. Suggestion to check, please. Thanks.

Hopefully this will be a quick fix and I won’t have to replace the fuel pump. Thanks!

Nice video thanks

Guy i bought it off of did the distributor, plugs and cables I’ve done tbi rebuild, injectors, iac & temp sensor getting ready for a fuel pump but i might have to get these ground cables a look, 1989 chevy scottsdale 2500 5.7 140,000 miles starts and runs but stalls randomly, loss of power also randomly, even randomly stalls after idling a couple minutes sometimes

I got a chevy 92 caprice 305 with electric gremlin gas vent issue if i have a pulse but no throtlle it stalls an puffs back at tbi

Thanks for the info!!

My 93 Chevy van cranks, no start! No pump prime. Fuel pump is only a couple years old..after watching your vid, I’m going to check all the grounds I can find...thanks!

Having this problem on 87 new relay. I checked the 2 wires at the pump the ground coming from the harness was not solid.

Great video very helpful. Is there a ground also back at the fuel pump under the bed?

Wow this dude solve my issues I have a 1992 s10 blazer ,I left them ungrounded and wonder why I been have starting issues

Ik this is old but thx bro this really help me and I am 22 I just bought. This truck thx 🙏

thanks Boss im currently chasing wires on my 1993 2500 just had a new pump installed 3 months ago and a puff of smoke shut me down today

Seeing lot of comments on grounds & hots while chasing my own issues, Up by the fuel pump relay under that harness cover is all your "hots" on the firewall, I'm reading tons of comments those are almost hand loose from the factory, I just checked; mine were not that tight also, cleaning them up tomorrow.. Couple more grounds, ones behind the distributor area from motor to firewall area, also ground strap near the starter..

Thanx,, got to clean all grounds

I just did a swap from a 5.0 to 5.7. I’m getting spark no gas tho I’m hoping it’s just a ground. I will check tomorrow thanks for the vid hope it helps me. Just out of curiosity my 5.0 ecm will run the 5.7 correct? Just maybe a little lean?

My fuel pump is humming im getting fuel behind the tbi but my injectors aren’t spraying i checked all my fuses all good i do have my ground to my battery i just dont have the little ground connected anywhere can that be my problem?

i recently purchased a 1995 c1500 w/t with a 4.3 votec wasnt getting fuel so i replaced the fuel pump in the gas tank its getting gas up to the throttle body now but the throttle body doesnt seem to be working

Is this for a 91 caprice to?

Thanks thumbs up

My fuel pump is working and got fire off sparkplugs and won't start but wants to. This truck was running fine then just died like I shut the key off any help would be appreciated

Thank you 👍

What about the engine coolant temperature sensor. I have had problems with starting and it shutting off going down the road

Thank you

How do I test these? With a multimeter right? I need to find good info on using one to check these things cause I'm having some issue

I could really use your help on a separate issue...can't figure out missfire on 95 GMC k1500...

Great video! My truck will crank all day and not start. Already checked all the fuses and the relay. In the process of removing the tank on my 1990 K1500 Silverado. I get 12.5 volts at the relay but only 5.5 volts at the pump. Been on Google for hours and can't find anything about the correct voltage at the fuel pump. I'm guessing it should be 12 volts. The tank has a bad leak so needs replaced anyway. Going to replace the fuel pump and pickup assembly while its out. Any insight would be appreciated.

I’m having a problem with my 98 Chevy suburban it takes a long time to turn on.

I’ve got a 1993 TBI Chevy K1500 it cranks and fires up but after a couple seconds it dies. I can get it to stay running but it doesn’t run well. I’ve replaced the fuel filter, air idle control, throttle body, map sensor, engine coolant temp sensor, cap and rotor, ignition coil and ignition module, egr valve and egr solenoid. And it still is doing the same thing. Any guesses?

I got 95 gmz 5.7 idles fine n smooth dnt stall but sputter around 80 stile at 40 km I change fuel filter tps clean carburetor

I have a 1985 Blazer, I replaced the sending unit, I'm replacing the gas pump and my next thing will be the carburetor, because the Blazer running really bad 😞 sounds like fireworks coming from the carburetor, what is your take on this??

Quick question...before u fixed ur ground, was ur fuel pump turning on still??

Basically a 4.3 vacuum line for egr and the wiring probly would help it's on a 1989 Chevy 1500

I just did a motor swap and now I’m not getting any fuel on the tbi I’m going to have to double checked all those grounds tomorrow thanks great video

Mine drives fine but when trying to cruise it just makes this tapping, chugging sound after it warms up. It's a remanned motor with only 6k miles on it. I've replaced the tbi gasket, TPS sensor, IAC valve, EGR valve, map sensor, knock sensor, ignition coil, and almost everything else. I'm at my wits end with it. Gonna check my grounds on it tomorrow.

Mine did the samething, this morning went out, just would crank...Went and bought a fuel pump relay, but I'll check the grounds first..Thanks

Thank you.

Thanks for all your videos. So I have an 87 Chevy Silverado and I can drive it for 20 , 30 miles or more and no issues, but if I shut it off it won't start until it cools off. Then it starts right up. I also noticed that I can't hear the fuel pump after I turn it off . Once, the engine cools off I am able to hear the fuel pump priming the system . Any idea.

Thanks !

Hey man what exactly is that lil fuse holder the one you said to check the ground on after the relay ?? I have no power going there I wanna know exactly what it is

I’m having the issue that my gauge is not reading correctly.

I'm having to floor my truck after it gets warmed up to start it again after running to the store sometimes. Do you suggest any common problems with this issue

Will not a full ground keep my 93 Chev 4.3 from running good how to check for good ground ,i when

Great video, I'm having trouble with my 90 silverado I put another used engine supposed to be good, cause first engine got messed up and now when I tried key it only cranks, don't hear the fuel pump. I think I put every single sensor right everything looks good but won't start, I'll see when I come back from out of town and do what you did. I'm kind of lost on those grounds near the water outlet and on ac compressor on mine. Help

I'm chasing a won't start after shutting off when hot randomly or will randomly stall when idling... figuring a ground up front is my cause as fuel pump is running but injectors not squirting. Dump a splash of fuel into the TBI and she will catch.

What do you check the wires with

My injectors are working and my truck will turn over and eventually it will crank but it would be really weak like sputtering I changed the fuel filter I was about to change the fuel pump but I saw this video my ground on the left side of the fuse box is corroded this could be my problem too right

love how jerryrigged these cars are usually yet never die. maybe wont start one day but spend 20 minutes reading the manual and youll figure out how to gete'r running

I got a 95 gmc my fuel injectors get constant power and ground and dump fuel through intake could throw in the rite direction

Had static in my audio speakers thought they were cracked also gauges didn't work properly found a ground that wasn't grounded. Fixed. Ground issues are 90% of problems.

Help !!! My 1990 chevy turns on fine however when i accelerate is stalls like no gas goes thru.

I changed my pump. All fuses and the relay are good. No fuel coming out of the injectors. The day the pump went out the injectors were spraying fuel out. Replaced the pump now no fuel?

Okay but why is my fuel pump staying on after turning of my engine? Also making my battery gauge read high

I’ve cleaned a couple of grounds and new fuel pump relay. Going to clean those two you showed us tomorrow. I have a multimeter but don’t know shit about it please tell me how I check that orange wire for power

I have a 1996 gmc 1500 that will not start. It starts if gas is poured into throttle body.

I have a 1990 Chevy and it turns on fine. But when you put in reverse or stop or come to a stop while driving it idles down and sometimes turns off. Any suggestions? We’ve replaced the fuel pump as well already.

Ok. I havent checked the relay or grounds. I went ahead and replaced the pump and strainer. Turn over, no start. Pump is running though. No fuel getting to the tbi. 1988 gmc 1500.

Howed you test the fuel relay the orange wire thanks

thers also a ground for your fuel pump on the drivers side at the rear frame .

My fuel pump is humming but I still ain’t getting fuel well

i ordered a new fuel pump relay and it didn't fix it. I didn't even think about checking these. Thanks for the vid

I need help please! I cant figure out on my 1995 K1500 suburban tbi My truck suddenly won't let me go faster than 35mph When I finally made it home When I parked it my truck aggressively shakes and die Every time I start it. It has a full tune up also rebuilt throttle body/ new egr/ no vacuum leaks an my pump does prime I just can't figure it out what's wrong, I know my timing is perfectly fine I'm so Confuse.. any ideas you may know?

oh i have a question,how do you check the ground im about to give this up ,everybody says check this check that ,show me

Your engine looked same as identical to mine

How do you check the ground

I own an 88 sierra single cab long box. Motor swapped to a 94. My truck died 3 times in way home. Died in front of 2 cops. Ill check my fuel, batterey and alternator

I've got an 89 Blazer 5.7 with tbi. New fuel pump, filter, injectors twice!, rebuilt pressure regulator, new Idle air control sensor, map sensor, throttle position sensor and new ECM! The grounds all look ok. It is still running way to rich at idle... It was running fine and all of a sudden started running like hell. I thought it was water in the fuel because the filter was full of water. I dropped the tank again! Drained all the fuel and water and ran acetone through the tank to help evaporate any water before putting it back in. I'm so frustrated and tired of throwing money at the problem

I change my fuel, injector , fuel pressure, regulator idle air And still running, like it’s not getting no gas

Nah bro I owe you something Iv been looking all through stuff I almost just bought a fule pump nothing talks about these wires as soon as I seen the ground next to the water pump part I went out looked at mine in gusse what it’s snapped inhalf I put a new connector on it boom she started right up

Hey I have a 93 Chevy and my injectors won't shot gas!!!

My gmc has 2 relays one under hood and one on side of battery

Help a brother out man..Rebuild a motor. First time. No gas to injectors, I hear a click and it turns , But dont hear the pump although relay is good.

Fuel injectors spraying after truck is turned off. Truck won't start.

My fuel pump won’t turn off

The fuel isn't getting to the injectors is not enough power or pressure to pull the gas to their I'm told by an ominous people it is the fuel pump

i have a gmc sierra 1992 i have a video on my youtube channel it has the tbi 454 if you could go and watch that video and tell me what you think it may be that would be awesome

Have power on orange wire have power on middle plug at fire wall for 15 sec. Pump may run for weeks then not run for weeks no rhyme or reason for it to stop or start pump is 3 yrs old

People tell me I could take the whole truck bed off I have a 99 Chevrolet 2500 3/4 ton truck how the woman going to do that

My 1987 one spras and don't shut off

Fucking battery ground..😂

Too bad he never says how to test the fuel pump
