So for the last week or so I've noticed my car sputtering

I was idling in front of my house and it just died
I was cruising and it just died

Each of those times it started again but I had to give it some gas as I turned the key

I didn't drive the car all weekend and I tried to start it this morning and it just wouldn't. It'll crank and it DOES start for half a second as it sputters and dies

I actually made it about 10 ft driving before it died again and it took 5-6 cranks and giving it gas before I could park it back where I had it

I hear the fuel pump (walbro 255) priming
I see it's getting fuel pressure (40-45)
It's getting spark because it does start just stumbles and dies

AFR does show lean when it's on idle but fine under load

What are we thinking peeps?

I think you should remove the engine, ship it to me, I'll diagnose it in my EG hatch as a daily driver, and send you a D16 in the meantime.

$amGD3

Lol I don't think you want my engine. I don't even want my engine

Alternator going bad?

$amGD3

I did just change the alternator belt about 2 months ago hmm

ignitor failing?

Your fake wheels are killing the car




And the tuning industry.

$amGD3

That'll prevent it from starting like EVER though right?

The car does start (sometimes) but sputters and dies

Can you datalog on your ecu?

When it dies you need to get out and see what's failing. Could be a loose wire from the icm to the ecm. Could be a loose wire from the ecu to the fuel pump relay.

Distributor cap? Take it off and clean it. If it's getting clogged up with scoring I could see it causing that issue.

Clogged IACV or fuel pump going bad. My Integra did this when I first bought it.....it turned out to be the fuel pump. And yes, it would still prime. It just wouldn't stay pumping enough to keep the car running.

Also, maybe a bad main relay?

Last time the fuel filter was changed?

$amGD3

Unfortunately i cant

Cap is also about 3 months old so i doubt it, but will check

I've never checked the IACV since I've had this car, will definitetly check that

Looking into pump and relay as well

Distributor?

Changed the redirect so it will still show in GDD when you click. Redirect will be for a longer period for this case only.

Since my other thread was moved and died

update from yesterday

b16a2,log manifol/turdbo,RC550s,Walbro 255

I've been having this issue where the car randomly dies,literally

I left it parked all weekend,Monday morning I tried to start it and it'll start but wont stay on. It starts for a brief second but sounds like its not getting enough fuel, i tried to give it some gas as i turned the key but no luck

After work I tried again and it started right away

I let it idle for about 10 minutes and it died on its own. I kept my eye on the fuel pressure gauge and even when it died, it never lost pressure,lowest point maybe 35psi

Tried to start it again and if I didnt give it any gas as I turn the key, it wont start,but if i give it some gas it starts

I let it sit and idle maybe 4-5 more times, after about 10 minutes,it just dies on its own everytime. It starts again every time by giving it some gas while turning the key..


I'm ruling out alternator because battery would've been drained after all this but it wasnt
I dont think it's ignition related because it does start, just sounds like its not getting enough fuel, (BUT GAS PRESSURE GAUGE SAYS PRESSURE DOE)
Fuel pump can be heard priming


My buddy and I literally stood by the car dumbfounded

Any CEL's?

stevieteg

I had a dead spot in the ignition of my eg. If the key moved just a little bit it would die.

I had to put the key in just the right spot to keep the car running.

Does it die when your driving?

Doesn't sound like it but maybe also the main relay?

$amGD3

No CEL

$amGD3

It does die when i'm driving, scared the **** out of me when it died in the middle of the highway when i was cruising at 80, thank god it started again lol

Actually it died yesterday after I got it to start for the first time after driving 10ft from my parking spot


I have a spare main relay but how would I check to see if it's bad?

1 2 NV

coil going bad perhaps? the problem is its so intermittent thats the hardest way to track down a problem.

$amGD3

Yeah that's why my buddy and I were so confused.

Nothing seems wrong,starts up, drives fine

it just dies on its own without warning

If it were the coil or any part of the ignition system, wouldn't the car not be able to start? Rather than start but dies after however long it's been running?

pull the ecu and check the pins. I had a 90 prelude that died on me randomly while driving and gave me fits trying to crank it back up. ended up just selling it and the guy had it running a couple days later.

he had to cut/splice the ecu connector as a couple pins corroded off inside the connector. they were barely making contact apparently.
