Sensor tested good (at the sensor). Interestingly, it has a shim despite being outside the "first 500" range.

What year is the car? Did you check the fusible link powering the ECM by the battery ?

I had this issue on a barn find 91 so I have been threw these series of test, mine was a slight Bent pin and corrosion on the DIS wire harness connector.

The injectors seem to be firing, so ECM would have power.

Had the connectors out when I swapped in the other DIS to test, but I'm leaning towards a chewed wire/short, or corrosion on a connector. I had put dielectric on all the seals under the plenum last time I had it apart to do injectors.

Still no spark. Running out of things to check. All wires on engine bay side test good.

Does your check engine light come on solid with key on engine off?

No spark, but at least you have spork!

Sorry, I could not help myself. I won?t quit my day job. [emoji38]

Nothing to add, but I hope you get it resolved.

It should flash once before solid light.
