Test NS-5B - Inspecting Fuel Pump

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. 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 . For wiring diagrams, see WIRING DIAGRAMS section.

Turn ignition off. Disconnect fuel pump relay. Turn ignition on. Using scan tool, check voltage on fuel pump relay connector terminal "A" (Dark Blue wire).
If voltage is less than 10 volts, repair open Dark Blue 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 Figure . If resistance is more than 100 ohms, replace fuel pump relay. Perform TEST VER-1. If resistance is less than 100 ohms, repair open Dark Blue/Yellow wire. Perform TEST VER-1.
