Thumbs down LT1 probs: will start then die

need some advice from anyone who wants to...

car will start, then die, as if its starved for fuel....have tried MAF, fuel pressure is 36 psi, fuel filter not too long ago, plugs wires recently....

funny thing is it runs fine once it gets started....only prob is when i start it....oh ya, sometime it will start without a problem....this car is possessed!

any suggestions, post up!!

mine did that, iac valve i think. how bout if you get it to turn over then give it some gas to keep the rpms high? mine started then wanted to die. also could be the opti.

Arrow Fuel pump relay

Hey there, my LT1 did the same thing, I replaced the fuel pump relay and IAC and it worked.

Good luck
Kevin

you guys think this would help cure hard starts? like overly long cranking b4 firing? runs fine once it starts, just hard starts all the time, unless started just a couple minutes after shutting off then it fires right up

thanks
