Wiring diagram says the circuit goes from Battery+ through the ASD relay to the coil, to the PCM to one of the two PCM grounds.
Following the circuit with 12V at the battery:
I get 7V at the coil from +pin to -pin with IGN on.
I get 12V at the coil +pin to -battery with IGN on (no voltage when off).
At the above suggestion, I tested the relay and also swapped relays with no change...
[This tells me the ASD is functioning and the relay contact is good]
[[Overall, this tells me the + side of the circuit is good.]]
I got decent resistance from PCM -pins to -battery. (Traced to a corroded ground point near the DS fender. FIXED)
[No change to problem]
I get no resistance from PCM -pins to -battery.
[PCM is grounded OK]
The -coil wire to PCM pin tested with no resistance and no shorts to ground.
[electrically, the - side circuit is OK, excluding the PCM]
All of that basically tells me that the PCM isn't grounding out the coil properly.
Any arguements or suggestions are very welcomed.
