CCM code 54 "Cranks does NOT run"! '90 MY - ZR-1 Net Registry Forums

The VATS (crank) is fine. I've used an Interrogator to check key and supply the VATS resistance to enable crank but I've no "fuel".

I have no other codes except a H41 (communication) and occasionally there is a communication problem on my Tech1. I've nearly got the CCM in my hands and I'm going to attempt the rest of the diagnostics this week-end likely.

I'm interested in maybe this resolution. Can just the "fuel enable" be programmed out of the PROM for the ECM. If it can then I might consider removing the secondaries and just have a PROM done to accomplish everything.

I've ordered a simple "fuel enable VATS by-pass" to just get it running if I have no luck in the diagnostics. It's not a solution I'd like to use permanently, I understand there can be and likely will be maybe "SECURITY" lamp issues. Don't know!

Not knowing if the car is a 30Hz or a 50Hz signal to the ECM I ordered a dual wave. There's comments everywhere that indicate both!

There's a 10 pin connector, engine harness to instrument panel (right side of instrument panel) I believe that I've not put my hands on either. Can someone maybe point me towards it!!
