Inspection

INSPECT FUEL PUMP




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

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

If the result is not as specified, replace the fuel pump assembly.

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

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

If the pump does not operate, replace the fuel pump assembly.
