Pinpoint Test KA: Fuel Pump (FP) Relay: Introduction

This pinpoint test is intended to diagnose the following:

• FP relay (9345)
• inertia fuel shutoff (IFS) switch (9341)
• harness circuits: B+, VPWR, FP, GND, FPM, and FPPWR
• 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.
