WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, 1995 Dodge Caravan, and 1995 Chrysler Town & Country. 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 at the end of this article.
- Turn ignition off. Disconnect fuel pump relay. Turn ignition on. Using scan tool, check voltage on fuel pump relay connector terminal ignition output circuit (Dark Blue/White wire). If voltage is less than 10 volts, repair open Dark Blue/White wire. Perform TEST VER-1.
- If voltage is more than 10 volts, 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.
