Like I said early in the thread.
Test the fuel pressure.
To correctly test the fuel pressure, test it with the engine it RUNNING.
Until you cross that off the list, we are wasting time, because it sure sounds like a low fuel pressure problem.

So, you think the fuel pump works at higher volume/flow, but not at low volume/flow? It sure works fine at anything above 750 RPM when in gear, AND at 750 RPM when out of gear. I'll look for the Actron fuel pressure test rig. I've had an Acton timing light for 30 years and still works great!
And what about the zero temp reading? That can't possibly have anything to do with a failing fuel pump. IIRC, I got that once before, but it started working after I turned it off, then back on again. Records show the digital dash was repaired once, and replace with new (or reman) later on.
