The check engine light was flashing with the switch on, not running, turned key off and back on light was steady, and would crank. Now check engine light does not come on. I have checked all fuses, all good, unless there is a hidden one. I can't pull codes because of no check engine light.
Do you
have the same problem?

Hi wmbrgi, Welcome to 2carpros and TY for the donation

I can't pull codes because of no check engine light.

On many cars, the ECM (that's the electronic brain) is on the same fuse circuit as other electrics like the cigarette lighter/accessory port. The lighter is prone to blow fuses on some vehicles, and if there's no juice going to the ECM, it can't tell you what's wrong.

Check and test fuse no.24 30amp and fuse no.1 5amp in the PDC this is the one that powers the PCM see below
