PINPOINT TEST KA: Fuel Pump (FP) Relay: Introduction
This pinpoint test is intended to diagnose the following:
- fuel pump relay (9345)
- inertia fuel shutoff (IFS) switch (9341)
- harness circuits: B+, VPWR, FP, GND, FPM, and FP PWR
- powertrain control module (PCM) (12A650)
The VPWR and FP circuits may be reversed in the harness connector. Refer to the appropriate SYSTEM WIRING DIAGRAMS article for schematic and connector information.
