I just want to say if it wasn’t for you, I wouldn’t fix my Honda fuel problem. I tried so many stuff and it was the computer. Thank you and keep doing a good job.

Had same problem had to wait 15 to 20 for fuel pump to prime other vidoes said capacitor did that no luck saw your vidoe and i tried it and it worked right away now no more waiting thanks soo much for sharing

I just ran into this same problem right now Thanks for the video brother really appreciated

THANK YOU SO MUCH !! You saved me a lot of money! It is the IC17 TA8903SN emulator i heated it up a bit with a heat gun and the fuel pump had absolutely no delay at all! I will now switch that out but I will find someone with experience to do that for me. THANK YOU AGAIN YOUR THE MAN!

I just fixed this issue. I swapped from obd2 to a chipped p06 a while back and it started having the same issue. Sometimes it would take 8min with key on before it would prime. My obd2 ecu had no issues so I swapped that chip and walla primes immediately every time

Thanks for the info. I got a p28 socketed for a s300 as well, was having the same problem. Had it in my lsv turbo ek, thought I had a short in my fuse box wiring cuz it kept blowing fuses. Took the ecu out put it in my integra and it turned over but wouldn’t start, just like my ek but it just didn’t blow fuses. Imma try this trick out sometimes and let you know it it goes.

Thank you my over seas brudda was having the same problem changed ecu and bang its working

I think I have this same problem. I have a 92 Integra that has starting issues out of nowhere. I don't hear the pump prime and car just cranks. I replaced the fuel pump with a Denso pump, drove it for a lil bit with no problems. The issue came back and I wasn't sure why. I replaced the main relay since I always carry a spare. Then I verified the relay was good by checking all the signals and hearing the clicks. I verified the pump is good by powering it directly. I checked continuity from relay to pump, relay to ECU. When I removed the ECU the area was wet, fixed my water leak and figured the ECU might've gotten shorted. Oredered another ECU from Ebay but the issue was still there. Found a corroded ECU ground at the thermostat housing, cleaned terminal, replaced bolt, verified continuity to ground is good. The issue is still there. It's an intermittent problem. When I checked the signals at the relay, I wasn't getting an ECU signal at times. This is probably my issue! It makes sense because I would drive it to work and turn it off and on as soon as I would get there to make sure it starts (car/ECU was still warm). Once it was time to go home, it wouldn't start (after the car/ECU cooled down). I'm going to order that chip. I'll update when I confirm if it worked or not.

Great video! I saw that other video as well just had my heat gun today. I need to order a new chip but I’m terrible with sodering

gracias desde uruguay es como tu dises tengo ese problema y lo resolvi gracias a ti gracias

I had this exact same thing in my 92EG si with a GSR swap I had a grams fuel pump brand new new fucking relay and I’ll always have this issue when I was cold I would have to disconnect my fans because they ran directly just leave the key open for 15 to 20 minutes then the fuel pump with prime and I’m in ca Central valley it ain’t that cold out here lol never could figure it out I just lived with it

Hey SI RICKO, could you send a link or add the product name for that chip your ordered? I’m having the exact same issue

Can you also link the component where to buy it from and what the chip is called

That’s exactly what I did after I found a video on KZfaq before yours. But was the same thing, just heating up the damn little thing and starts like a champ.

where you buying the replacement ecu parts to solder in?

Yep had the same problem with my p28 too. Wow. But I would have to put my key in the on position and let it set for 2 or 3 minutes before it would prime. Mostly in the mornings when it's cold out. I live in CA. But most of the time it would start right up. But sometimes it would fuck me. So I took out the ecu sprayed it down a good cleaning and I have never had the problem again.

Thats how some perfectly 92-95 civics end up at the junk yards with new dizzys , fuel pumps etc etc that the “mechanics” think it is and make people spend thousands and then end up at the junk yards

I will try this out hopefully thats it, my 00 civic is not priming changed with new fuel pump and still not prime checked all the fuses and test good even changed the ignition fuse because I saw some corrosion but sill nothing even changed the main relay hopefully the chip is bad on mine also thanks man

Pumped dude! I ordered 5 of those things. I replaced and re chipped another ecu only to have the same issue. So then I put in my original p28 and it worked, only to have the same issue again. Every time it got cold lol

Thank you and God bless you

Thanks Ricko ☝️

In my case its the opposite. Car starts every time in the cold & one random hot day the fuel pump will not prime what so ever.

could you post a link to where you bought new capacitor ? or also if not a hassle make a video how you did it. thanks

Damn I got an auto and swapped it to manual and having fuel issue. Car is turning fine but no fuel and relay is clicking when turning over but no fuel at all. Gonna try the heat gun rn

i have mini-vtec d15b, i had issues on expired unleaded fuel due to pandemic was not able to use the car for a long time, then my fuel line hoses broke down, hard starting, noisy walbro fuel pump. so i changed all the fuel hoses from my fuel rail, gas tank & fuel filter. i cleaned the throttle, drained the expired fuel changed it to premium gas, changed the air hoses. now the pump noise is gone & now engine is running okay but suddenly my check engine had a steady light when starting & had a rough idle. i tried to reset the ecu but it wont reset even i removed the ground terminal for 10mins. so i suspected the ecu might be the problem since we tried to plug my ecu to another car and still the check engine did not disappear and had the 2nd car running bad. when we placed the original ecu to the 2nd car it was okay, back to normal. so our suspect is my ecu is at fault. the next day after filling up my mini to a full tank of premium gas the check engine is gone back to normal again. but i still have my doubts on the ecu. so let me know where i can buy a reliable ecu obd1 out there..

Thank you bro im having this same issue I will try this cause Ive connected the pump directly to the battery, it works but its better to try this I let you know if I solve the issue whit this

My EG civic has the same problem. And my problem is that it is pretty hard to find a working TA8903SN chip. I recently bought one from AliExpress but it is not original IC. The car started with it but only in safe mode. (can't get the custom rom run). Do you know a good source to find good IC17?

i connect my fuel pump directly to the battery with a switch would that affect my honda hatch98 b16. its starts up

Nice! Where can I order one of those to re solder??

--hi I have a Honda EG fuel pump not priming, pump, the main relay is ok I already changed the C14 capacitor, now could it be the IC C17 TA8903? I f I have to get a new ECU, the engine is D16Y1, do I also need to get the Key assembly. ( Im from Australia and the car has immobiliser)

hi i have the same problem...with p30 ecu the guy how fix them told me that ... my question this is toshiba chip? i cant find to buy :((((

Did some of your dash light not come on as well?

OK guys if u need a replacement look up jason water tuning they sell replacement for this chip ur thank me later 😅👍🏻

Need more vibes Bro

That happens when water leaks in the passenger foot well underneath the cowl there's a drain that gets clogged and causes it to leak that's why I take my hondata out before it rains otherwise the ecu board will get wet and start shorting $h!t

I'm having this exact issue with my Mazda 3 , I've replaced my ecm lately and this problem has showed up when it got colder outside

Thats my problem too in my p06 chipped ecu can i use ebay ic17? My problem is the last number if the ic is not the same in ebay its TA8903SN 9513k the ebay got 1205k its okay to use that one?

Could that cause fuel pressure issue

What about having this problem when it’s warm ???

This is the great thing about youtube, sharing. Found the other guy, chip number is TA8903SN. Where did you buy yours? I already replaced all the caps on that board, plus the dual relay, same issue. I am thinking you and the other guy you referred to have the magic mushroom!

So how do we fix the problem or is the ecu just bad ???

See, my fuel pump WONT turn off and it’s causing crank no start. Anything on that?

i put a heat gun on my ecu and civic started right up. thanks

Yo I got the same problem

And saw the same video

yeah probly what happend to mine shit ass ebay reason why i dont buy from them

Wtf
