Electrical help need
Hello all,
I just got the car started for the first time in 4 years (finally!). And Ive hooked up an EFI system which includes a PDM that I’m trying to get hooked up. Now my issue is that my 12v ignition sources directly out of the fuse box have a constant 2.5 volts on them even with the key off which is cause the PDM to think the key is on so it in turn sends the signal to the rest of the triggers on the PDM. Any ideas on what could cause the constant voltage with key off?
