2GR-FE FUEL: FUEL PUMP: INSPECTION

INSPECTION

1. INSPECT FUEL PUMP





(a) Inspect the 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)
If the result is not as specified, replace the fuel pump assembly.
(b) Inspect fuel pump operation.
(1) Apply battery voltage to both the terminals. Check that the pump operates.

NOTICE:
- These tests must be done quickly (within 10 seconds) to prevent damage to the pump.
- Keep the 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.
