FUEL PUMP - INSPECTION
| 1. INSPECT FUEL PUMP |
Inspect the resistance of the fuel pump.
Using an ohmmeter, measure the resistance between terminals 1 and 2.
- Standard resistance:
- 0.2 to 3.0 Ω at 20°C (68°F)
If the result is not as specified, replace the fuel pump.
Inspect the operation of the fuel pump.
Connect the battery's positive (+) lead to terminal 1 of the connector, and the negative (-) lead to terminal 2. Check that the fuel pump operates.
- NOTICE:
These tests must be performed within 10 seconds to prevent the coil from burning out.
Keep the fuel pump as far away from the battery as possible.
Always turn the voltage on and off on the battery side, not on the fuel pump side.
