Fuel pump electrical, testing
Special tools, testers and auxiliary items required
- Hand held remote control (jumper).
- Multimeter.
- Electrical connector test lead set.
Test conditions
- Battery voltage 12.5 V.
- Fuse - 29 - in fuse holder at left of instrument panel is OK.
- Fuel filter OK.
- Ignition switched off.
Test sequence
- Remove the rear seat bench. Refer to 72 - SEAT - FRAMES .
- Remove cover retainers - arrows - from the right sealing flange.
- Disconnect the electrical harness connector - 1 - from the fuel delivery unit.
- Connect a Hand held remote control (jumper) to terminal - 1 - of the fuel delivery unit and to vehicle battery (+).
- Connect a jumper cable from an Electrical connector test lead set to terminal of the fuel delivery unit and to vehicle Ground (GND).
- Press switch on the Hand held remote control (jumper).
NOTE:
- The Fuel Pump (FP) runs quietly. Avoid surrounding noises while testing the fuel pump.
- Listen for an operating noise from the fuel pump.
Fig 3: Checking The Electrical Circuit Between Terminals Of The Fuel Delivery Unit And The Fuel Pump For Continuity
If no operating noise is heard:
- Remove the fuel delivery unit.
- Using a Multimeter, check the electrical circuit between terminals - 1 - and - 5 - of the fuel delivery unit for continuity.
Specified value: 0 ohms.
If a malfunction is detected in the electrical circuit:
- Check the electrical harness connector for damage, corrosion, lose or broken terminals.
- Repair the electrical circuit.
If no malfunction is detected in electrical circuit, replace the fuel pump.
- Install the fuel delivery unit.
End of procedure.
