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)

Fuel Pump (FP) Relay Connector 

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.
