So i drove to pick my girlfriend for lunch, car started fine when i left, drove for about 20 minutes never over 80mph car ran flawless like always. When we were leaving the resurant however i went to start my car and it started right up...but then died... So i started it again and again it fired right up then died... wtf!? it did it one more time to me, then on the fourth try it started up fine and ran great... I turned it on and off again like another 5 times before we left the parking lot and it was fine... WTF?
It started just fine then the RPM's slowly started to go down untill it died... Possible fuel pump problem? OR Something electrical malfunctioning? I dont get it, i've never even heard of this happening ever before, to anyone... thanks -------------------- 1 JL 1,000/1v2

usually when that happens its actually that its gotten too much gas. during cranking the PCM commands the ISC (idle speed control motor) to a certain position. if the ISC is dirty, faulty, or sticking then it wont open to the correct position, the engine wont get the right amount of air, but since during cranking to start the PCM doesn't read any airflow (it reads it, but does not use it) it doesn't know that the ISC is sticking/dirty so its injecting the normal amount of fuel for a closed throttle start. when you open the throttle wide or even partially you're bringing that air back to lean it out enough to get the engine started and running.
