Fuel Pump

INSPECT FUEL PUMP ASSEMBLY




a. Inspect the fuel pump resistance.
1. Using an ohmmeter, measure the resistance between terminals 4 and 5.

Standard: 0.2 to 3.0 Ohm at 20 °C (68 °F)

b. Inspect fuel pump operation.
1. Apply battery voltage to both terminals. Check that the pump operates.

NOTE:
- These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
- Keep the fuel pump as far away from the battery as possible.
- Always turn on and off the voltage on the battery side, not the fuel pump side.
