Fuel Pump: Testing and Inspection

FUEL PUMP OPERATION CHECK
1. Check the operation of the fuel pump by using the MUT-II to force-drive the fuel pump.
2. If the fuel pump will not operate, check by using the following procedure, and if it is normal, check the drive circuit.
1. Turn off the ignition switch.




2. Remove the fuel pump relay connector.
Connect the terminal number 2 of the harness-side connector to the battery.
Check if the fuel pump operation sound can be heard at this time.

NOTE: As the fuel pump is an in-tank type, the fuel pump sound is hard to hear, so remove the fuel filler cap and check from the tank inlet.

3. Check the fuel pressure by pinching the fuel hose with the fingertips.
