? reconfiguration of electrical connector ? are you referring to the de pinned plug at the ECM ?

Yes.

Have tested fuel pressure at the rail and showing between 40 and 45 psi. Checked for any faults at the ALD port by bridging A & B. Only getting code 12, so no faults detected.

HELP PLEASE. I have a Corvette function coming up in a couple of weeks and need the Z running.

Question.. Should the engine start and run if the cam angle sensor was faulty ??? I pulled it out again today ( 3rd time ) just to re check, and it looks as good as new.

OK, so fuel is apparently not the issue.
Can you confirm spark?

It has spark, as it does fire and run. BUT it only runs for a few seconds then dies. So someone is maybe shutting off Fuel or Spark for whatever reason. I don?t know. That?s why I?m here seeking suggestions. Desperate to get this up and running again . 😤

Hi Russel,

Are there any ZR-1 owners near you ? I would propose an ECM swap test at this point if possible.

Closest one would be approx 2 hours away. It?s my previous ?90 ZR-1.
My current non running Z has a Lingenfelter 495 package in it. My old ?90 Z is stock standard. Would this create an issue by swapping the ECM?s ??
