Grand Vitara, Vitara & XL-7
- Turn ignition on. If fuel pump is heard for 3 seconds, circuit is in good condition. If fuel pump is not heard, go to next step.CAUTION: Ensure jumper connections are made correctly. Improper connections may result in damage to PCM and wire harness.
- Turn ignition off. Using a fused jumper wire, connect Pink/Black wire and Blue/Black wire terminals at fuel pump relay connector located on right side of engine compartment. Turn ignition on. If fuel pump is heard, go to next step. If fuel pump is not heard, check Pink/Black wire or Blue/Black wire for an open or poor connection. Repair as necessary. If wire and connections are okay, replace fuel pump and retest system.
- Turn ignition off. Remove fuel pump relay. Using DVOM, measure resistance between fuel pump relay terminals. See Fig 1 . Continuity should not be present between relay terminals "A" and "B". On Vitara, resistance between relay terminals "C" and "D" should be 79-95 ohms at 68°F (20°C). On Grand Vitara and XL-7, resistance between relay terminals "C" and "D" should be 70-110 ohms at 68°F (20°C). Continuity should be present between relay terminals "A" and "B" as battery voltage and ground are applied to relay terminals "C" and "D". If resistance is as specified, go to next step. If resistance is not as specified, replace fuel pump relay and retest system.
- Check for poor connection or open in Blue/Black wire or White/Green wire to fuel pump relay. Repair as necessary. If wire and connections are okay, replace PCM and retest system.
