FUEL PUMP ASSY
a. Insect fuel pump resistance.
1. Using an ohmmeter, measure the resistance between terminals.
Resistance: 0.2 - 3.0 (Ohm) at 20 °C (68 °F)

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

NOTE:
- These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
- Keep fuel pump as far away from the battery as possible.

Always do the switching at the battery side.
