2001 z28 would not start a couple weeks ago and eventually got it started
We ordered and installed a OEM Crank sensor and did a relearn in it and it is doing the same thing.
Car has fuel pressure, but we Checked for spake while it was not starting and had no soak .
We hooked the scanner up again and it started.
Any ideas ..

 

I take it the scanner did not report any codes? I not familiar with FBody harness routing, but with GM truck main harness if not supported, will wear the wires. Common for intermittent/no start condition as the harness loom studs poke through the harness sheathing and damages wires. Just a thought
