Re: starts & dies
Were the heads touched? If you had any work done to them, the rockers may be too tight. It's not the most likely solution, but it's a possibility.

Re: starts & dies
Try swapping your fan relay and fuel pump relay or, there should be a red spade connector near the same area that I believe if you power will power the fuel pump. It's a test port or something. I'm not 100% on what you do with it thought, apply power or something else.

Re: starts & dies
Mine did the same thing (87 Iroc L98 TPI). Try disconnecting the MAF sensor and if it starts and runs,may run like $hit but it's a start. If this works,check your MAF power relay. Mine was junk and the car would start and immediately die.

If you start it and give it gas will it run?
P.S. - Your post about losing the fuel pump after the car is running and then starts back up again doesnt sound right either.
