Car turns over then dies after starts Today I started my 99 trans am and it idled fine then suddenly died..I tried starting it again and it turns over and immediately dies..I hear my fuel pump turning on and working but it seems like it just cuts off the fuel pressure when it starts. I start the car it does a rev to 1900 and just dies and then I hear the fuel pump sending more fuel up..so I try to start it again and it just revs up and dies. I have recently done a cam swap on it and it ran perfect, it just randomly shut off this morning. Any help would be great!

Seems like it's cutting fuel for some reason after it starts.
Check your MAF, pull it off and clean it with CRC Mass Air Flow Cleaner.
Check to see if your security light is flashing.
What are some recent thing you've done to the car? a little background information may go a long ways.

I have checked my maf and it is very clean. My security light is not flashing or anything..the only things I have done to the car is a cam, fast 92 intake, 92mm tb. Svo 42 lb green top injector, slp lid, 1 3/4 in pacesetter longtubes with a 3in off road x-pipe. It's just weird because it ran fine for 3 weeks with absolutely no problems...and it decides to act up today..could it have anything to do with my fuel filter?

Put a fuel pressure gauge on that ******.
Although a pressure gauge wont tell you flow, its a good starting point.
It maybe a fuel filter..
No vacuum leaks or anything? or it doesnt run long enough to run out & listen?

You really need a scanner of some sort to see what it's doing. Outside of that, with as an extreme condition as it is (as in not running), a visual inspection under the hood should give you some insight. Kinda sounds like a big vacuum leak.
