If the result is not as specified, replace the fuel pump.

Inspect fuel pump operation.
1. Connect a battery positive (+) lead to terminal 2 of the connector, and a negative (-) lead to terminal 1. Check that the fuel pump operates.
NOTE:
- These tests must be performed within 10 seconds to prevent the coil from burning out.
- Keep the fuel pump as far away from the battery as possible.
- Always switch the voltage on and off on the battery side, not the fuel pump side.
