Fuel Pump Amperage Test: Cherokee

  1. Perform FUEL PRESSURE TEST  and FUEL PUMP VOLUME TEST  before performing this test. If fuel pressure and fuel volume are okay, ensure fuel tank has fuel. If fuel tank is empty or near empty, amperage readings will be incorrect. Ensure fuel tank temperature is more than 50°F (10°C).
    WARNING: With ammeter installed in place of fuel pump relay, fuel pump will be activated even with ignition off. Before connecting ammeter, ensure all fuel lines and fuel system components are connected.
  2. Remove fuel pump relay from Power Distribution Center (PDC). See Figure. Set ammeter to 10-amp scale. Connect negative lead of ammeter to terminal C2 (Dark Green/White wire) at fuel pump relay socket in PDC. See Figure. Connect positive lead of ammeter to terminal C1 (Dark Green/Black wire) at fuel pump relay socket in PDC.
  3. If fuel pump current draw is 10 amps or more, replace fuel pump module. See FUEL PUMP MODULE under FUEL SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION article. If fuel pump current draw is less than 10 amps, fuel pump module is okay.
