Roy,
Here's what I have done so far. The transmission went out this winter, I removed it, had an expert rebuild it, then re-installed it, ran like a trooper for months. Drove it into work one, ran great. Went to leave work it would not start, no fuel pressure at the Schrader valve. Replaced the fuel pump, filter, and relay. Ran normal all that afternoon and on the way to work the next morning, that afternoon it would not start again, good pressure at the Schrader.
I replace the distributor cap, rotor, and coil, and found a broken MAP sensor on the top of the intake, replaced that as well. It still cranks over just like always but it will not run. Replaced the PCM with a reconditioned (pre-programmed to the VIN number) and followed the set up instructions, still nothing.
I replaced the crankshaft sensor yesterday, she still cranks over but will not start.
The driver's window has a decal that says "Chapman code security system", however I am not the first owner of this truck and do not know if this is the original window. The truck came with a plain metal key (not even a plastic head), and over time I have had some other keys made, none with a chip in them, she has always ran fine, could this be a cause? Would it somehow become active after all these years? If so how can it be disabled?
Someone at NAPA suggested it might be a pick up under the rotor.
Thank you for your time Roy, and anyone else who reads this.
