Re: Passlock System

PassLock system has nothing to do with spark or fuel pressure....in some cases it can prevent cranking or not send a fuel enable signal to the PCM which prevents the injectors from firing, but it doesn't stop fuel pressure...

Re: Passlock System

I am at loss. My wiring circuits test good. the data lines are good. But the pcm does not turn on the fuel, ignition or the any of the 5volt reference signals. I have all the key and ignition voltages to the pcm and the grounds also to the pcm and the DLC. Why oh why? What can I test.
