I received my ECM back from Auto Computer Specialist. Was told NOT to hook it up until I found the short to ground.
Of the things I checked was the grid heater solenoids. My voltmeter was reading 12v across the big lugs on both of them. Thinking it was bad, I replaced them with OEM type, NO Ford solenoids. I am still reading 12v across the two bug lugs.
TPS is NOT hooked up.
ECM is in but NOT hooked up.
The relay in the PDC is NOT installed.
The two smaller wires on each solenoid ARE hooked up.
I have found and cleaned up 4 grounds in the engine compartment.
i have not had the alternator checked yet.
Any help will be greatly appreciated.
