Ok, take two...

Fixya says that 85 shouldn't get ANYTHING with the key off, no continuity at all. I have continuity to + and - with key on or off. I tried to check continuity with b30 and got nothing. Assuming b30 is the 30 hole on the middle connector on the pcm. So there's a problem.

30 works as it should. Voltage with key on or off.

86 gets no volts with key object or off.

Diagnosis?

Wire at C2 Pin 30 (middle connector on the pcm, trans relay control circuit) should be pink...... Did you test the correct wire?

So from here to....



Here...i should have continuity right?



Would the solenoid have anything to do with not getting power to the relay? If it doesn't i'm about to tear into the harness and trace this pink wire all the way over.
