INSPECT FUEL PUMP ASSEMBLY
a. Check the resistance.
1. Using an ohmmeter, measure the resistance between the terminals.
Resistance: 0.2 to 3.0 Ohm at 20°C (68°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.
