How to Test the Electric Fuel Pump?
Step 1. Locate the fuel pump in the fuel tank
Step 2. Turn the key to the run position and listen if any buzzing coming from the fuel pump. If no sound, proceed to Step 5
Step 3. Set the amperage on voltage meter and place the clamp on the positive wire to the pump
Step 4. Start the vehicle and record the amperage reading. Then compare the reading to manufacturer’s specifications
Step 5. If the pump did not turn on at all, remove the electrical connector on the pump
Step 6. Set DC volts on the meter, place the positive meter lead on the terminal of the positive wire in the connector and the negative meter lead on the terminal of the negative wire
Step 7. Turn the key to the run position, if the voltage reading is same as battery voltage, then the pump has failed
The steps are for reference only, and we we recommend you to ask the technician to do the test or replacement.
