P0522-vehicle not in park or neutral during KOEO test

P0542-Fuel Pump Circuit open-PCM to motor ground

Diagnostic Aids
When ignition switch is in the ON or START position, the PCM connects FUEL PUMP circuit (PCM terminal No. 22) to ground. The fuel pump relay is energized and electrical current flows to the fuel pump. If PCM does not receive ignition PIP signal within 2 seconds, FUEL PUMP circuit is opened and fuel pump operation is terminated. Perform this test when instructed by QUICK TEST or CIRCUIT TEST AA. This test is only intended to diagnose:
? Fuel pump relay.
? Inertia Fuel Shutoff (IFS) switch.
? Wiring harness circuits (B+, VPWR, FUEL PUMP, GND and POWER-TO-PUMP).
? Faulty Powertrain Control Module (PCM).
