Pontiac Forum - Pontiac Discussion Forums - Problem: Won't stay running

It has been "down" since May. It will turn over and start but only runs for like maybe a second and seems to shut itself off. I tried the pass-code relearn on it two months ago several times and one time that MAY have been what got it to run but who knows. It stayed runnin and i backed it out of my parkin spot at my apartment overflowing with excitement it had worked. Then backed it into another visitor's spot only to have it die soon as I put it in Drive. So i started it up and it stayed runnin again and put it in drive, died again instantly. Now it will not stay running again. Its got spark, the fuel pump comes on, the alternator is good, battery good, fuses are all fine. I've gotten a replacement computer from a running car and had it reflashed at a GM dealer. The dealer reflashed it and spent 2.5hrs diagnosing it only to tell me verbatim: "Sir we have absolutely no idea what's wrong with your car." Which I thought quite odd since they're a damn dealer mechanic and dismayed cause how the hell am I SUPPOSED TO FIGURE IT OUT? If anyone, I mean ANYONE can help me i'd be more indebted to you than you know.............Please HELP!!!!!!
