Friends,
I am humbled by this issue and need to ask for help. I don't want to resort to a shop or just simply replacing stuff randomly in desperation.
Here's the details:
1) 1985 / Auto / 107K miles /
2) Engine died while traveling at 50 mph on even road. No prior signs of trouble or abnormality before failure.
3) The fuel system will now prime the engine to 38 psi, start and run for approx 4 seconds.
4) When the engine dies the fuel pressure drops to zero simultaneously.
5) I have replaced the fuel filter, fuel pump and filter, fuel pressure relay and connector pigtail, oil pressure sending unit, and MFC. Nothing changed the symptoms.
6) Oddly, no trouble code is being issued. Computer displays the 12 code and nothing further.
I read the write up thread listed by the Grumpy Corvette guy. .....Really good info, the answer may be right in front of me, but I have not solved it yet.
I understand 1985 was the only year to use a burn-off module. Does anyone know how to test one of these on the car? I recently purchased a used module off ebay, but would like to test the original before I remove it from the car.
Is there something else I should be checking at this point that would cause this problem?
Thanks,
Lance
