Crazy Electrical issue with EFI system

Cameroonski · 04-30-2010, 01:45 AM

I switched out the ECU and the ignition switch today and still no luck. All my relays are good, they have been tested and switched and juggled and they work. My problem is this...

M-REL only has .08 volts at the computer, as well as at the EFI main relay with the ignition on. When I apply voltage to the computer side of the the resistor side of the relay, it works and the car turns on but with funky idle issues.

What i will do tomorow is do this bypass and see if im getting voltage at M-REL... i think. If i am, I know the wire is good, if not there is another problem somewhere else and im SOL.

Cre, thanks. Any other advice? I am totally confused here...
