I have a 1994 Thunderbird LX that won't stay running. It will CRANK and RUN, but for only 30sec - 2min or so, then SHUT off as if someone is hitting a kill switch. I at first thought it was a faulty fuel pump so I replaced it and the fuel filter with no luck. I was told by several people that it could be the crankcase position sensor. I replaced it and have the same issues, runs then shuts off. I was told by a ford tech that it could be the computer module located behind the passenger headlight. I replaced it, same thing. Runs for min or 2 then shuts off. I have checked fuel pressure and it's getting 30-35lbs of pressure. I don't want to sell my tbird because it's too nice of a car and it runs pretty good, WHEN IT'S RUNNING. Can anyone please assist and advise me on where to look next? I am sure it is simple, but I have made it seem so complex.
