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

Faulty map sensor?

It could be that or a whole bunch of other possibilities.

I wouldn't take it anywhere unless it happens again.
If the car is running fine the tech will have a hard time [if he can] finding the problem, and you'll most likely waste $$.

What you can do [while you're waiting for it to do this again] is find your diag box under your hood. Get a SMALL paper clip, you don't want to force the terminals in the box.
Jump TE2 and E1. Note, TE2 isn't a typo. If you don't understand this, do a search for how to check codes. It's the same thing, except to normally check for codes you jump TE1 and E1. You're going to jump TE2 and E1.

AFTER you jump the terminals, turn the key on and drive the car.
Take it for a drive to the mall, whatever, just make sure you get some good time and varied driving. I'd say at least a half hour.

Stop the car, turn the key off, remove the jumper and jump TE1 and E1 and see if you got any codes.
If not, there's not a whole lot you can do at the moment.
If you did, that most likely gave you an idea of the problem circuit.

1 thing to try is sometimes cars have tough starts, saw that once ever in my car, your problem sounds exactly like mine. when you turn the key over, put some gas into it until it stabilizes. It should stay on and you probably won't see that problem again. I bought like fuel system cleaner after that.

next time it happens, try holding the throttle wide open when cranking and then as soon as it starts ease back off.

That happened to once to me too... 1st try it run and died, second time run and died again, seems like its not getting enough gas so on my third try I step on the gas pedal while cranking it and reved it once in a while when it started running. Works fine after that.

I had this prob too at work, the motor was normal temp, turned it off, then started backup 2 more times, 3 try gave it gas, let it idle at 2000 for a few secs, let off and it was fine.

Never did anything about it, and havent had the prob since.

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.

ok thanks alot,guys its just that ive never had that happen with any car... If anything like that happens again i will let vou know

Thanks

Is there a way to clean this? I've been having this problem for a while now.

Yes, remove the throttle body, remove the valve and clean it out.
Spray PB Blaster or Deep Creep in it and let it sit for a few hours.
A SMALL wire brush will help as well.

When you remove the valve you're going to have a small coolant flood, just so you're aware...
