Hi Dan,

This sounds much more like an immobilizer/security authorization problem than a starter problem, especially since bypassing the starter relay makes the engine crank but it still will not run. We need to run the codes first, here is a video to help us get started.

In live data, check whether the PCM shows something similar to “Start Allowed,” “Valid Key,” or “SKIM/SKREEM Fuel Enabled.” If we don't start this way we will be guessing. Let me know.
