idles for a few seconds then dies

[mikepc]

car starts and idles for a few seconds then when the idle does down to settle it starts sputtering and you can hear the iac start opening to keep it running but it just dies out. if i try to give it gas it will dies right out. fuel pressure is good at 48psi. tried uping it but still no change.

any ideas?

It's a long shot but you could have a clogged fuel filter.

tps might not be working right mine does that

Has a new fuel filter. Tps is working because I can start it and rev it it to 4000rpm then it'll just drop and die

What are you using to regulate the fuel pressure? I checked your profile, but you didn't have your specs fully listed. If you are boosted, you might look for boost leaks, from there I would go to crank sensor.

Charge pipe is disconnected , I'm using a areomotive afpr. And portfueler.

Where is the crank sensor located?

Just by the oil filter.
Is this a new problem and just start happening out of nowhere or did you make any changes to your setup?

Car was running fine , then was topping up the fluids then let it run for 15 min to checks leaks, shut it off and went to start it that's when it started messing up

Key dance code 43 came up. So there's a good chance it's the crank sensor

Crank sensor sounds right thats how my car acted when mine was going out. If you pull it out and look at it mine was made of plastic and the plastic was cracked where the magnent was, probabily causing it to fail.

All crank sensors made for our car are made of plastic. I don't know why....and I call dibs on calling it first!

OP: Why did you have the charge pipe disconnected? You know that's potentially bad for your turbo, right?

 

[Lightning_0809]

The new sensor i bought auctually has a metal sleeve around it. I think it was bwd brand from orilleys.

WHA?!?!!!111ONE111? Glad at least one manufacturer pulled their head out of their ass...

 

[mikepc]

Charge pipe was off to clean up wires underneath , I never drove it disconnected. I'll replace the crank sensor tomorrow. Haven't had time lately due to getting hit riding the gsxr

Replaced crank and map sensor , still same problem. Car flashes key dance code 43 twice

 

[mikepc]

Any other ideas why my car would be flooding it's self so much it's dies.

My 98 GS is doing kinda the same thing. Do you have to hold the pedal to the floor to get it to start?
I changed MAF sensor, checked all vacuum lines for leaks, cleaned the TB thoroughly and seafoamed it. After each
Thing I did, it ran better....for a day. Also had a bad thermostat....was stuck open, so it didn't warm up.
That was the best fix so far. Ran like new and the cel even went off.....for a day. Now its right back to running super rich.
Plugs were black.
My next guess is O2 sensor, then maybe ecu.

My car did the same shit!I replaced every sensor possible and changed the plugs and wires but nothing helped.So I went and pulled out my FP and saw that my tank was full of water.I bought $30 worth of water from the gas station.I ended up getting a check for $945 from their inssurance com. to pay for everything.You might not see the water in the tank,but there might be some at the bottom.

Posting here because it's similar to what I'm having going on, without a CEL. Sometimes, like once every 4-7days I'll go out in the morning (35-45*) and warm it up. It'll just flat out die after idle for 15seconds, sometimes it takes a few minutes. While driving it's been known to just die, but feels like fuel cut. I've never first hand known what a fuel cut is but it's the best way I can describe it. I only assume so because sometimes it will feel really laggy, and other days, especially warmer ones, it takes off like a bandit without an issue.

Now, my Eclipse's Fuel pump does the prime "noise" when you key over. However, if it dies from fuel cut, I try to start it again, and I get no prime "noise" and it'll just turn over without starting, wait 5-10minutes, and it's back alive, prime noise and all. I'm a little puzzled because I feel like it could be both the pump and the filter.. and the 420A pumps on the Eclipses...are too pricey for me to buy both right now... any help would be greatly appreciated.
