Fuel Pump Ballast Resistor: Testing and Inspection

FUEL PUMP RESISTOR INSPECTION [13B-MSP]

Resistance Inspection

CAUTION:
- If a tester lead is inserted forcefully into a terminal during resistance measurement, the terminal may deform and cause a decrease in the contact pressure between terminals while the connector is connected. When measuring resistance, attach a tapered lead or wire to the tester lead and lightly touch the terminal with the tip.






1. Disconnect the negative battery cable.

2. Remove the fuel pump resister. Service and Repair

3. Verify that the continuity between the fuel pump resister terminal A and B is within the specification.






Fuel pump resistor continuity
- 0.304-0.336 ohms [20 °C {68 °F}]

- If not within the specification, replace the fuel pump resistor. Service and Repair
