Erratic Has Settled

Moxie refused to start at all today.

Several clunks like the (new) battery was dead.

Several solid sounding cranks but stopping before start.

Wiggled the harness going to the PCM.

Started!

Moved her to the inlaws to make way for Halloween activities.

Scanned for codes.

Cleared these codes four times and they came back four times.

We're getting someplace figuring her out!

That I don't have the equipment to find a GMLAN broken wire... it's a problem.

Need to find a shop I can trust to do a thorough diagnosis.

    DVOM and a wiring diagram. And maybe a set of jumper wires and some T pins. T pins can be gotten at any store that sells sewing supplies.
    Do it the old fashioned way...

    alldatadiy.com for a wiring diagram and flow charts for the DTCs. It's professional grade repair information. Well worth a subscription.
