Fuel Pump: Testing and Inspection

FUEL PUMP OPERATION CHECK

1. Check the operation of the fuel pump by using the scan tool to drive the fuel pump.
2. If the fuel pump will not operate, check by using the following procedure. If normal, check the fuel pump drive circuit.
a. Turn the ignition switch to OFF.
b. When the fuel pump drive connector (black) is attached directly to the battery, check if the sound of the fuel pump operation can be heard.

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

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