Fuel Pump Relay By-Pass Procedure

WARNING: This page is about a different car, the 1994 Cadillac Fleetwood. However, it is still accessible from the selected car via links, so may be relevant.

If fuel pump will not energize, relay may be by-passed to test fuel pump and related wiring. See Fig 1 . Turn ignition off. Disconnect fuel pump relay connector.
Using a fused jumper wire, apply battery voltage to fuel pump test connector (located in engine compartment). For fuel pump test connector location, see COMPONENT LOCATIONS at end of this article. See Figure .
If fuel pump runs and relay tests okay, check for faulty connections at relay. If fuel pump does not run, check for faulty wiring between relay and fuel pump or replace defective fuel pump.
