Gas engine
The fuel pump relay is located in the central unit located under the instrument panel on the driver's side. Relay location #4 (see fig. 4A.19).
Remove fuse #28 (protects the fuel pump) from the fuse box located on the left side of the instrument panel (see fig. 4A.18).
Connect an LED tester to ground and one of the fuel pump fuse terminals.
To access the relay box, remove the cover at the bottom of the instrument panel on the driver's side.
Turn on the starter, while the fuel pump relay should turn on with an audible click and the LED probe should light up.
If the relay does not turn on, check the relay control circuits.
If the relay turns on but the probe LED does not light, connect the probe to another fuse post.
If the tester LED does not light up again, check the continuity between terminal 23 of relay 4 (pic. 4A.20) and if the circuit breaks, restore it.

If the relay control circuit is OK, then the relay is faulty and needs to be replaced.
Checking the voltage supply
Remove the fuel pump relay 4 (pic. 19) from the central relay box.
Turn on the ignition.
Connect a voltmeter in turn to the following terminals of the relay base:
- between pin 19 (plus from the ignition switch) And «weight»;
- between pin 17 (battery plus) And «weight».
Voltmeter should show 12V (battery voltage). Otherwise, restore the appropriate electrical circuits.
Checking the control circuit
Connect the LED probe between pins 16 (motor control regulator) and 17 (plus) relay base (pic. 4A.19).
Turn on the starter, while the probe should blink. Otherwise, the relay control circuit is damaged and must be repaired or the motor control regulator replaced.
Install the fuel pump fuse.
Install the cover at the bottom of the instrument panel on the driver's side.
