My '91 vert died on the freeway a few weeks ago, and my mechanic just gave up. Here's everything I know:
It died smoothly, dropping in RPMs without any noises etc. From then on, it cranks but doesn't start. According to my mechanic, the O2 sensor and main relay were both fried. He also says that it fried the DME, but I don't think he's removed it, and when I took it out it the circuit board looks totally clean.
Mechanic says it's not the fuel pump or crankshaft sensor, so I've ruled those out. He says it's a short in the engine wiring, as you can hear a brief click when you plug in a good main relay. The click comes from the alternator/alternator wires—is a click normal, or evidence of the problem?
I figure if the alternator area isn't supposed to click on connection then that's my problem, and I need to figure out how to get the engine wiring harness off so I can rewire. But if not, I'm lost. Any advice is very much appreciated, and if pics or more details would help let me know!
Thanks,
Alec
