Notice
Replace the fuel pump relay if the measured value is over
9A. Notice
Check the fuel filter and fuel line when the fuel delivery is
not within specified value.
Measure the Current Consumption of Fuel Pump
1. Remove the fuel pump relay from fuse and relay box in
trunk, and turn the ignition switch to "ON" position.
2. Using a multi-tester, measure the current consumption by
connecting the terminal No.1 and No.3 of pump.
Measure the Fuel Delivery From the Fuel Pump
1. Disconnect the return pipe from fuel distributor and insert
the appropriate hose into it.
2 . Place the hose end into the beaker with the minimum capacity
of 1Liter.
3. Turn the ignition switch to "ON" position.
4. Connect the terminal No.33 and No.5 of ECU with a service
wire.
5. Measure the fuel delivery from the fuel pump.
