2004 Saab 9-3 Fuel Pump Fuse Location: Complete Guide to Finding and Fixing Your Fuel Delivery Issue
If your 2004 Saab 9-3 cranks but won't start, the fuel pump fuse is one of the first things you should check. The fuel pump fuse for a 2004 Saab 9-3 is located in the passenger compartment fuse box, which is behind a cover on the left-hand end of the dashboard (driver's side). The specific fuse is number 14, rated at 20 amps, and it powers the fuel pump directly. This guide will walk you through exactly where to find this fuse, how to test it, and what to do if the fuse is fine but your fuel pump still isn't working.
Where to Find the Fuse Boxes in Your 2004 Saab 9-3
The 2004 Saab 9-3 has multiple fuse boxes, and knowing where each one is located will save you a lot of time. The second generation Saab 9-3 (also known as the YS3F or 9440 platform) has four distinct fuse panel locations.
Passenger Compartment Fuse Box (Dashboard End Panel)
This is the most important box for fuel pump troubleshooting. It is located on the end of the instrument panel on the driver's side of the vehicle. To access it, open the driver's door and look at the left end of the dashboard. You will see a small hatch or cover. Simply pull it off to reveal the fuse panel. There is even space for spare fuses inside this hatch.
Engine Compartment Fuse Box
There are two fuse boxes in the engine bay. The main one is located between the front bumper and the battery. The second, smaller unit is located right in front of the battery beneath a protective cover.
Luggage Compartment Fuse Box
The trunk fuse panel is located on the left-hand side of the luggage compartment behind a cover. This box handles rear door modules, trailer lights, seat heating, and the radio amplifier.
The Exact Fuel Pump Fuse Location and Rating
Here is the most critical information you need for the 2004 Saab 9-3 fuel pump circuit:
Fuse Number: 14
Amperage Rating: 20 Amps
Location: Passenger compartment fuse box (end of dashboard on driver's side)
Fuse number 14 is listed as protecting the "Radio, sound system I; control panel, Infotainment System" in some official diagrams, but according to multiple owner reports and troubleshooting guides, this same fuse also powers the fuel pump on the gasoline models. One detailed fuel pump replacement guide confirms that the fuel pump is powered through fuse #14, located on the fuse board at the left side of the dash.
On the 2.0T and Aero models (petrol engines with the B207 engine), this fuse provides power to the fuel pump relay and then to the pump itself. The wiring diagram for the 2004 Saab 9-3 Aero shows that the fuel pump relay is located at the right kick panel, and fuse 14 feeds power through that relay to the pump.
Step-by-Step: How to Check the Fuel Pump Fuse
Before you start buying expensive parts, follow these steps to verify whether your fuel pump fuse is the problem.
Step 1: Locate the Fuse Panel
Open the driver's door and remove the plastic cover on the end of the dashboard. You can use your fingers to pry it off; no tools are needed.
Step 2: Find Fuse Number 14
Look at the diagram printed on the inside of the fuse panel cover or on the fuse box itself. The fuses are numbered. Find position number 14. It should be a 20-amp fuse.
Step 3: Visually Inspect the Fuse
Remove the fuse using the plastic fuse puller tool that is usually clipped inside the fuse panel cover. Hold the fuse up to the light. Look through the clear plastic top at the metal wire inside. If the wire is broken or melted, the fuse is blown.
Step 4: Test with a Multimeter (More Reliable)
Sometimes a fuse can look fine but still be bad. Use a multimeter set to continuity mode. Touch one probe to each of the two small metal prongs on top of the fuse. If you hear a beep, the fuse is good. If there is no beep, the fuse is blown.
Step 5: Test for Power at the Fuse
With the multimeter still in your hand, set it to DC voltage (20V range). Turn the ignition key to the "ON" position (do not start the engine). Touch the black probe to a good ground (like a bolt on the door hinge) and the red probe to each of the two metal prongs on the fuse. One side should show battery voltage (around 12 volts). If you have power at the fuse but the pump is not running, the problem is likely the fuel pump relay or the pump itself.
What to Do If the Fuse Is Blown
If you find that fuse number 14 is blown, do not just replace it and hope for the best. A blown fuse is a symptom, not the root cause. Something caused that fuse to blow.
- Replace with the Correct Amperage: Always replace a blown fuse with a new one of exactly the same rating. Using a higher amp fuse can cause electrical fires. The correct rating for this circuit is 20 amps.
- Check for Short Circuits: If you recently worked on any electrical components in the car, especially near the fuel pump or radio, check your work for bare wires touching metal. One owner reported that stripping wires to install a tuning box created a short that blew this fuse.
- Test the Fuel Pump: If the new fuse blows immediately when you turn the key, the fuel pump itself may be shorted internally. This requires replacing the pump.
- If It Keeps Blowing: Have the electrical system checked by a Saab specialist. If the same fuse blows repeatedly, it indicates a major fault that needs professional diagnosis.
The Fuel Pump Relay Location
If your fuse is good but you still have no fuel delivery, the next component to check is the fuel pump relay. According to the wiring diagrams, the fuel pump relay for the 2004 Saab 9-3 is located at the right kick panel (passenger side footwell area). This relay controls power delivery to the fuel pump once the engine control module (ECM) signals that it is safe to start.
To test the relay, you can swap it with an identical relay from another circuit (like the horn relay) and see if the fuel pump starts working. If it does, the relay is bad and needs replacement.
How to Confirm It Is the Fuel Pump and Not Just the Fuse
Here is a tried and tested method from a Saab owner who went through the same troubleshooting process:
- Remove the rear seat cushion: The bottom seat cushion is just clipped in. Pull up firmly on the front edge to release the clips. No tools are needed.
- Find the access hole: Under the seat, you will see a plastic cover (about 4 inches in diameter). Pull off this cover to access the fuel pump electrical connectors.
- Identify the 4-wire connector: There are two connectors under the seat. One has three wires and one has four wires. The 4-wire connector is the one you need. The two thicker wires are the power supply for the pump. The green/black wire is the power from fuse 14, and the black wire is the ground.
- Test for voltage: With a multimeter, check for 12 volts between the green/black wire and the black wire while someone turns the key to the "ON" position. If you have voltage here but the pump does not run, the pump is bad.
- Direct power test: Run power directly from a 12-volt battery to the pump-side of those two thick wires. If the pump runs for a few seconds and then dies, it is failing and needs replacement.

Common Mistakes to Avoid When Replacing a Fuel Pump
Replacing a fuel pump on a 2004 Saab 9-3 is a job that requires attention to detail. Here are the most common DIY mistakes:
- Not replacing the fuel filter: Always replace the fuel filter at the same time as the pump. A clogged filter can cause a new pump to fail prematurely.
- Using the wrong pump assembly: The Saab 9-3 fuel pump assembly includes the pump, sending unit, and the plastic housing. Many owners recommend replacing the entire assembly rather than just the pump to avoid future issues.
- Ignoring the fuel level: Running your car on a low fuel tank is hard on the fuel pump. The fuel helps cool the pump. Running out of gas even once can significantly shorten the life of your fuel pump.
- Forgetting to check the fuse and relay: Do not buy a new pump until you have thoroughly tested the fuse, relay, and wiring. Many people replace a perfectly good pump when the real issue was a corroded relay contact.
Final Thoughts
Tracking down the 2004 Saab 9-3 fuel pump fuse is straightforward once you know where to look. The fuse is located at position number 14 in the driver's side dashboard fuse panel. It is a 20-amp fuse that also powers other accessories. If your Saab cranks but refuses to start, start your diagnosis with this simple fuse check.
