INSPECTION

1. INSPECT FUEL PUMP




a. Check fuel pump resistance.
1. Measure the resistance between the terminals.
Resistance: 0.2 to 3.0 Ohms at 20 degree C (68 degree F)

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

NOTE:
- These tests must be done within 10 seconds to prevent the coil from burning out.
- Keep the fuel pump as far away from the battery as possible.
- Always turn on and off the voltage on the battery side, not the fuel pump side.
