2006 Buick Lucerne.
Engine size = 3.8 v6
Dash lights service engine soon codes p2761, p0748.
Question = I have the service engine soon light on the dash of my 2006 Buick Lucerne. I had it scanned and the codes come up p2761, and p0748. Also it does not start sometimes. Can you please help with these problems, i absolutely love this car. Thanks you.
Thank you for the tip/donation.
These codes are transmission related. There is a common wiring problem that can cause intermittent no crank or start and these transmission 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.
