car starts then dies

[jw_55_55]

OK been having a few problems with my car lately and seeing if anyone can help out. Heres whats going on. Got my car tuned two weeks ago and everything was fine, brought it home drove for a week them starting having problems with the fuel pump. Fixed the problem and drove the car for another week and then started having trouble with my gm maf. Replaced and drove fine for a couple hours. Then the car will try to start go get to 1500 rpms then just die. Thought it was the cam angle sensor so i replaced that and worked for about an hour and now same problem. It seems like when its cold it will keep running.(not sure if its related) But once the problem kicks in I cant get ny car re-started. I have dsmlink v3 and no codes are coming up and i did a log and nothing seemed out of the ordinary. PLEASE HELP wanted to take the car to the drag this weekend!!!!

Coil packs are known to fail when warm. Could be causing you to run extremely rich and die.

Does it start everytime when it's cold? Does it crank for longer than usual?

Doesnt crank any longer than usual and I have a brand COP setup on it....so i dont think they would fail on me already. Also when i open the ecu to check for bad caps how can you tell if they are good or not??

I didn't even think about the ecu and I just went through an ecu problem a couple months ago. Follow this link it has some good info, and make sure you check the back of the board also.
