Inspect fuel pump operation
1. Apply battery voltage to both the terminals. Check that the pump operates.
  NOTE:
  - These tests must be done quickly (within 10 seconds) to prevent damage to the pump.
  - Keep fuel pump as far away from the battery as possible.
  - Always do the switching at the battery side.
