Test NS-5B - Inspecting Fuel Pump

WARNING: This page is about a different car, the 1994 Plymouth Acclaim and 1994 Dodge Spirit. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY TABLE . For wiring diagrams, see WIRING DIAGRAMS .

Turn ignition off. Disconnect fuel pump relay. Turn ignition on. Using DRB, check voltage on fuel pump relay connector terminal "A" (Dark Blue wire (AG and AJ bodies) or Dark Blue/White wire (AP and AS bodies).
If voltage is less than 10 volts, repair open in appropriate wire. Perform TEST VER-1 . If voltage is more than 10 volts, go to next step.
Using an external ohmmeter, check resistance across fuel pump relay terminals. See Fig 1 . If resistance is more than 100 ohms, replace fuel pump relay. Perform TEST VER-1. If resistance is less than 100 ohms, repair open in Dark Blue/Yellow wire. Perform TEST VER-1.
