Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Good evening, Confirm the injector circuit tests ok between the injector and the Engine Control Module. Verify the injector is not going open after the misfire has developed. To verify the above, backprobe the Powertrain Control Module terminal 64, Yellow/Black on connector 1. Expect battery voltage. If the above tests are ok, replace and program the Engine Control Module. The Engine Control Module is covered under an 8/80 warranty.
Run through the tests and you are most likely looking at a bad PCM I know its over 8 years but I try to tell everybody about the warranty as it sometimes falls within the time frame. Please open and print all the attached pdfs. Thanks.
8 years 80k miles, after sending it I realized it was a 2005 and its already 2016.
