Fuel Pump Relay

This 4 or 5-terminal relay is located in underhood fuse/relay box. Fuel pump relay is used to power in-tank fuel pump. When ignition is turned to ON position, fuel pump relay sends signal to in-tank fuel pump for 2 seconds. When engine is started PCM receives signal from ignition control module (Passport, Rodeo and Rodeo Sport) or 58X reference signal (Axiom and Trooper). PCM signals fuel pump relay to operate in-tank fuel pump. For terminal identification, see appropriate wiring diagram in WIRING DIAGRAMS article. For testing procedure, see RELAY TESTunder MISCELLANEOUS TESTin appropriate SELF-DIAGNOSTICS article.
