Test 17A - Pump Motor Circuit Not Working Properly

1994 Plymouth Sundance Base, 2D Hatchback, 2.2 D, AutomaticSECTION Test 17A - Pump Motor Circuit Not Working Properly
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagram, see WIRING DIAGRAM.
  1. Turn ignition off. Remove and inspect pump/motor relay fuse (cavity "F"). See Figure. If fuse is faulty, go to TEST 17B. If fuse is okay, go to next step.
  2. Reinstall pump/motor relay fuse. Turn ignition on. Using DRB, actuate MOTOR PUMP. If pump/motor can be heard running, go to TEST 17C. If pump/motor cannot be heard, go to next step.
  3. Using DRB, actuate MOTOR PUMP again. Put DRB in voltmeter mode. Using DRB, backprobe Brown/White wire at pump/motor relay connector. See Figure. If more than 9 volts are present when relay energizes, go to TEST 17D. If less than 9 volts are present when relay energizes, go to next step.
  4. Using DRB, stop MOTOR PUMP actuation. Disconnect pump/motor relay connector. Inspect, clean or repair connector as necessary. Ensure ignition is on. Put DRB in voltmeter mode. Using DRB, check voltage on Dark Blue wire at pump/motor relay connector terminal "D". If reading is less than 10 volts, repair open in Dark Blue wire. Perform TEST VER-1A. If reading is more than 10 volts, go to next step.
  5. Using DRB, check voltage on Brown/White wire at pump/motor relay connector terminal "B". If reading is less than 10 volts, repair open in Brown/White wire. Perform TEST VER-1A. If reading is more than 10 volts, go to next step.
  6. Using DRB, check voltage on Gray wire at pump/motor relay connector terminal "A". If any voltage is present, replace pump/motor relay. Perform TEST VER-1A. If no voltage exists, go to next step.
  7. Turn ignition off. Disconnect CAB 37-pin connector. Inspect, clean or repair connector as necessary. Put DRB in ohmmeter mode. Using DRB, check resistance of Gray wire at pump/motor relay connector terminal "A". If resistance is less than 5 ohms, repair short to ground in Gray wire. Perform TEST VER-1A. If resistance is more than 5 ohms, go to next step.
  8. Using an external ohmmeter, check resistance of Gray wire between CAB connector terminal No. 3 and pump/motor relay connector terminal "A". If resistance is less than 5 ohms, replace CAB. Perform TEST VER-1A. If resistance is more than 5 ohms, repair open in Gray wire.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • β€’ You smell fuel, burning insulation, or see smoke.
  • β€’ Brakes feel soft, pull hard to one side, or make grinding noises.
  • β€’ The engine overheats, stalls repeatedly, or misfires under load.
  • β€’ You are missing required tools, torque specs, or safe lifting equipment.
  • β€’ You are not confident in the next step or safety outcome.
