INSPECT FUEL PUMP ASSEMBLY

a. Check the resistance.




1. Using an ohmmeter, measure the resistance between the terminals.

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

b. Check the operation.
1. Apply battery voltage to both terminals.

Check that the pump operates.

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