2001 Suzuki Grand Vitara Fuel Pump Relay Location: The Complete Guide
The bottom line: The fuel pump relay on a 2001 Suzuki Grand Vitara is located inside the engine compartment fuse box, which sits near the battery on the right side of the engine bay. It is a brown relay, and the fuse box cover has a diagram that helps you identify it. The relay controls power delivery to the fuel pump, and if it fails, your engine will not start.
Knowing exactly where to find this relay and how to test it can save you time, money, and frustration. This guide walks you through the location, inspection steps, and what to do if the relay is bad.
Where Is the Fuel Pump Relay on a 2001 Suzuki Grand Vitara?
The fuel pump relay is mounted in the under-dash fuse and relay box, also referred to as the instrument panel fuse box. This box is located below the dashboard on the driver's side, near the kick panel.
For a left-hand drive vehicle, you will find the relay box to the left of the steering column. For a right-hand drive vehicle, it is located on the right side. The relay itself is a standard 4-pin relay that is the same design as the main relay used in the same vehicle.
How to Identify the Fuel Pump Relay
Once you open the cover of the fuse and relay box, look for a brown relay. According to owner reports and service manuals, the fuel pump relay is typically brown in color. You can also check the diagram printed on the inside of the fuse box cover. The relay is often labeled as "FUEL PUMP" or "FP" in the diagram.
If you are unsure, you can compare it to the other relays. The fuel pump relay has the same internal structure as the main relay, so it will look identical.
Step-by-Step Steps to Access the Fuel Pump Relay
1. Prepare the Vehicle
Park the 2001 Suzuki Grand Vitara on a level surface. Turn the ignition completely off and remove the key from the ignition. For safety, disconnect the negative battery cable before working on any electrical components.
2. Locate the Fuse Box
The fuse box is located under the dashboard on the driver's side. It is positioned above the kick panel, near the parking brake pedal or the hood release lever. You may need to sit on the floor to see it clearly.
3. Remove the Cover
The fuse box cover typically has a latch or clip on the bottom edge. Pull the cover downward to release it. Set the cover aside.
4. Identify the Relay
Look at the diagram printed on the inside of the cover. The fuel pump relay is usually in the center or right side of the relay box. It is a square component with four metal prongs on the bottom.
5. Remove the Relay
Once you have identified the correct relay, firmly grasp it with your fingers and pull it straight upward. It may require a gentle wiggle to release it from the connector.
How to Test the Fuel Pump Relay
Testing the fuel pump relay is a simple process that requires a multimeter and a 12V battery source.
Check the Resistance
Using a multimeter set to ohms, measure the resistance between terminals "C" and "D" on the relay. The specification is 79 to 95 ohms at 20°C (68°F). If the reading is outside this range, the relay is faulty.
Check for Continuity
Measure the resistance between terminals "A" and "B". There should be infinite resistance (no continuity) when no power is applied.
Test the Operation
Connect a 12V battery to terminals "C" and "D". The positive lead goes to "C" and the negative to "D". When power is applied, you should hear a click from the relay. Now, check for continuity between terminals "A" and "B". There should be continuity (zero resistance) when the battery is connected. If the relay does not click or does not show continuity, replace it.
Common Symptoms of a Bad Fuel Pump Relay
A failing fuel pump relay shows clear warning signs. Here are the most common symptoms:
1. Engine Cranks But Does Not Start
This is the most common symptom. When you turn the key, the starter motor turns the engine over, but the engine never fires. The fuel pump is not receiving power because the relay is not closing.
2. No Fuel Pump Prime Sound
When you turn the ignition key to the "ON" position, you should hear a faint humming sound from the rear of the vehicle for about 2 to 3 seconds. This is the fuel pump priming. If you do not hear this sound, the relay may be faulty.
3. Engine Stalls While Driving
If the relay fails while the engine is running, the fuel pump will lose power, and the engine will stall immediately. You may be able to restart the car after a few minutes if the relay cools down, but this is a serious safety concern.
4. Intermittent Starting Problems
A failing relay may work sometimes and fail other times. You may experience no-start conditions that come and go. This is often caused by worn relay contacts that cannot maintain a consistent connection.
Related Fuse Information
The fuel pump circuit is protected by a 15A fuse, which is also located in the under-dash fuse box. The fuse is labeled "FUEL PUMP" and is typically in position number 2 in the fuse box. If the fuel pump relay is working correctly but the pump still does not run, check this fuse first. A blown fuse is a common cause of fuel pump failure.
The Fuel Pump Assembly Location
If you have verified that the relay and fuse are good, the problem may be the fuel pump itself. The fuel pump on a 2001 Suzuki Grand Vitara is located inside the fuel tank. The fuel tank is positioned under the rear seat area. To access the pump, you need to remove the rear seat cushion, then remove the access panel on the floor. The pump is part of a module that includes the fuel level sender and float.
Why You Should Replace a Faulty Fuel Pump Relay
Driving with a bad fuel pump relay is not recommended. The relay controls a critical safety and engine function system. If the relay fails completely, you will be stranded. Replacing the relay is inexpensive and straightforward. The relay itself costs less than a new fuel pump, and it takes only a few minutes to replace.
