Fuel Pump

INSPECTION

INSPECT FUEL PUMP




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

Resistance: 0.2 to 3.0 Ohms at 20 °C (68 °F)

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

NOTE:
- These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
- Keep fuel pump as far away from the battery as possible.
- Always do the switching at the battery side.
