Intermittent ECU Electrical Power Loss

***ZGN*** · 03-20-2011, 01:47 PM

1992 RHD FD, with an intermittent ECU power loss problem that I am about to roll the car out of the garage and set it on fire.

It will intermittently loose power to the PFC ECU in which time the key is turned to the "ON" position the Power FC commander has no display, Odometer does not display, radiator fans do not turn on, no power to fuel pump. Radio has no power, windows do not roll down. What does work is the Starter, outside lights, and the annoying beep beep when key is in ignition.

I have checked and rechecked all grounds, reseated and checked all connections for corrosion.
I had to have missed something I just don't know what.

Any ideas?
