1JZ Won't Start on Engine Stand - Injector Power Wires Need 12V

Electricalintermediate✓ OP Confirmed

Problem

1JZ engine on an engine stand turns over but will not start, despite having the starter and fuel pump hooked up directly to the battery

Engine cranks/turns over but does not startStarter and fuel pump powered directly from battery

Root Cause

The injector power wires were not receiving 12V. The body harness plug has two black/orange wires that supply power to the injectors, and these were not connected to a power source.
