03 Silverado1500 cranks/no start 5.3liter

[Silveranbut]

Truck ran but stalled. No ignition pulse. No 5 volt reference to PCM. No codes with cheap scanner. Has fuel pump pressure

New parts:

Gas lines and gas filter

Crankshaft sensor

Camshaft sensor

PCM with VIN coded

Master window switch

A relay

Ignition switch

Tried relearn procedure

What could be the problem?

Did you use a test light on the fuses for the PCM in the fuse block?
