Test NS-5A: Checking Fuel Pump

NOTE: Perform TEST NS-2A before proceeding.

Turn ignition off. Disconnect fuel pump relay. For fuel pump relay location, see Fig 1. Using a voltmeter, check voltage on fuel pump relay connector fused B+ circuit. See Fig 1-Fig 4 . If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open fused B+ circuit. Perform TEST VER-1A .
Install a substitute relay. Attempt to start engine. If engine does not start, go to next step. If engine started, replace fuel pump relay. Perform TEST VER-1A .
Reinstall original fuel pump relay. Disconnect fuel pump harness connector. See FUEL PUMP CONNECTOR LOCATION table. Turn ignition on. Using scan tool, actuate ASD fuel system test. Using a voltmeter, check voltage of fuel pump relay output circuit at fuel pump connector (harness side). See CONNECTOR IDENTIFICATION . If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open fuel pump relay output circuit. Perform TEST VER-1A .
Turn ignition off. Using an ohmmeter, check resistance of fuel pump ground circuit at fuel pump connector (harness side) Black wire. See FUEL PUMP CONNECTOR (HARNESS SIDE) WIRE IDENTIFICATION table. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open fuel pump ground circuit. Perform TEST VER-1A .
If vehicle is a Breeze, Cirrus, Sebring Convertible or Stratus, go to next step. If vehicle is an Avenger, Neon, Sebring Coupe or Talon, replace fuel pump. Perform TEST VER-1A .
Inspect fuel pump jumper harness. If fuel pump jumper harness is okay, replace fuel pump. Perform TEST VER-1A . If fuel pump jumper harness is not okay, repair or replace jumper harness as necessary.
