Glad you got it fixed and thanks for the heads up on the battery terminal removal. I have to agree on the older non-computer vehicles.

I checked the bulb and it is good. So where do I look next? Or could the PCM be bad as the check engine light never illuminates? All help is appreciated!

Pinout #32 bk/pk wire is the check engine light driver I do believe mine had a loose connection there.
