In-Tank Pump Test

  1. Check continuity and resistance of in-tank pump ballast resistor. Resistor is at right top of cowl and should have 0.4 ohms resistance.
  2. Continuity should be present between one side of ballast resistor and pin 3 of pump relay connector (right fender well). Continuity should exist between other side of resistor and pin 1 in connector. Pin 5 should be grounded.
  3. Insert positive voltmeter probe into rear of relay connector at pin 3 while connector is hooked up. Connect other probe to ground and crank engine. Voltmeter should indicate 8-10 volts. Insert probe at pin 4 and crank engine. Voltmeter should indicate 9 volts. If not, check battery and supply to pump relay.
  4. If voltage is present, check continuity between pin 3 of relay connector and Dark Green wire at pump (fuel tank).
