JK:
Thank you for the tip/donation.
These codes are transmission related. There is a common wiring problem that
can cause intemittant no crank or start and these trans. codes. There is an area
under the hood where a main engine harness rubs through and damages
several different wires. This would be the first place to look.
I will send a pic of the area shortly.
Let me know if you do find some damaged wires and need help with the repair.
If wires look OK, then we can check a few other things......
