2006 Saab 9-3 Fuel Pump Relay Location: A Complete Owner’s Guide
**The fuel pump relay on a 2006 Saab 9-3 is located inside the main fuse box under the dashboard on the driver’s side, behind the cover near the steering column. ** If your car cranks but won’t start, or you hear no fuel pump prime when you turn the key, a faulty relay is often the first thing to check. This guide walks you through the exact location, how to test the relay, common symptoms of failure, and step-by-step replacement instructions so you can get back on the road without a trip to the mechanic.
The Saab 9-3 (2003–2014) uses a standard relay layout that has remained mostly consistent across model years. For the 2006 model specifically, the fuse box is positioned to the left of the steering wheel, behind a small plastic cover. You don’t need any special tools to access it—just a flathead screwdriver or even your fingers to pop the cover off. Inside, you’ll find a diagram printed on the back of the cover or on the fuse box itself, which labels each fuse and relay by number and function.
What Does the Fuel Pump Relay Do?
The fuel pump relay is an electrical switch that controls power to the fuel pump. When you turn the ignition key to the “ON” position, the relay closes and sends battery voltage to the fuel pump, which then pressurizes the fuel system. This is why you hear a faint whirring sound for a couple of seconds when you first turn the key—that’s the pump priming. If the relay fails, the pump never receives power, and the engine won’t start.
In many cases, a bad relay can also cause intermittent issues. The car may start fine when cold but stall when warm, or it may refuse to start after sitting for a few hours. This happens because the relay coil or contacts wear out over time, and heat or vibration can cause them to lose connection temporarily. Understanding how the relay works will help you diagnose the problem faster.
Where Exactly Is the Fuel Pump Relay Located?
The main fuse box on the 2006 Saab 9-3 is located under the dashboard on the driver’s side. Here’s how to access it:
- Sit in the driver’s seat and look below the steering column, near the footwell area.
- Locate the plastic cover—it may have a small notch or tab at the top or bottom.
- Pull the cover off by hand or use a flathead screwdriver to gently pry it. There are no bolts or screws holding it in place.
- Look at the diagram printed on the inside of the cover. It shows the layout of all fuses and relays in that box.
The fuel pump relay is typically labeled with a number or a symbol that looks like a small fuel pump or a lightning bolt. On the 2006 Saab 9-3, it is commonly located in the relay position 1 or position 2 in the under-dashboard fuse box, depending on the exact trim and engine configuration. The 2.8L V6 Aero model, for example, may have a slightly different layout than the 2.0T or 1.9 diesel versions.
If you don’t see the diagram clearly, check your owner’s manual—it lists every fuse and relay and their exact locations. The manual also provides tips on which spare fuses to keep in the car.
Symptoms of a Failing Fuel Pump Relay
Before you dive into replacement, make sure the relay is actually the problem. Common symptoms of a bad fuel pump relay in a 2006 Saab 9-3 include:
- No priming sound: When you turn the key to “ON,” you should hear the fuel pump hum for 2–3 seconds. If you hear nothing, the relay may not be sending power.
- Engine cranks but won’t start: The starter motor turns the engine over, but there’s no fuel pressure, so combustion never happens.
- Intermittent stalling: The car runs fine for a while, then dies suddenly. After waiting a few minutes, it may restart—this points to a relay that overheats and loses contact.
- Fuel pressure test fails: If you attach a fuel pressure gauge, you’ll see zero or very low pressure when the key is turned on.
- Check engine light: The ECM may set a code like P0087 (fuel pressure too low) if the pump isn’t running when expected.
Important note: These symptoms can also come from a failed fuel pump, a clogged fuel filter, or a bad fuel pump fuse. Always test the relay before replacing the pump—it’s the cheapest and easiest fix.
How to Test the Fuel Pump Relay
Testing the relay takes about 10 minutes and requires only a multimeter or a 12V test light. Here’s how:
1. Remove the relay from the fuse box.
2. Identify the pins: A typical automotive relay has four or five pins. The two smaller pins (coil pins) are what energize the relay. The two larger pins (contact pins) are the switch that carries power to the pump.
3. Set your multimeter to ohms and measure resistance across the coil pins. You should see a reading between 50 and 120 ohms. If it’s infinite, the coil is open and the relay is dead.
4. Apply 12V to the coil pins (you can use a battery or a power probe). You should hear a click as the relay closes.
5. Measure resistance across the contact pins while the relay is energized. It should read close to 0 ohms. If it stays high, the contacts are burnt and the relay needs replacement.
If you don’t have a multimeter, you can swap the relay with an identical one from the fuse box (like the horn relay or the wiper relay) and see if the car starts. If it does, the original relay is bad—simple as that.
Step-by-Step Fuel Pump Relay Replacement
Replacing the fuel pump relay in your 2006 Saab 9-3 is straightforward. Here’s the full process:
Step 1: Gather your tools. You’ll need a new relay (check your owner’s manual for the correct part number), a flathead screwdriver, and possibly a flashlight.
Step 2: Turn off the ignition and remove the key from the ignition switch. This prevents any accidental electrical shorts.
Step 3: Access the fuse box under the dashboard as described above.
Step 4: Identify the fuel pump relay using the diagram on the fuse box cover or your owner’s manual.
Step 5: Pull the relay straight out. Most relays are held in by friction—just grip it firmly and pull upward. Do not twist or force it, as you could damage the socket.
Step 6: Compare the old relay with the new one. They should have the same pin layout and part number. If they differ, check compatibility before installing.
Step 7: Push the new relay in firmly until it seats fully. You should feel it click into place.
Step 8: Replace the fuse box cover and reinstall any trim pieces you removed.
Step 9: Test the system by turning the key to “ON” and listening for the fuel pump prime sound. Then start the engine and let it idle for a few minutes.
What About the Fuel Pump Fuse?
The fuel pump relay works hand-in-hand with the fuel pump fuse. If the fuse is blown, the relay won’t help. On the 2006 Saab 9-3, the fuel pump fuse is also located in the under-dashboard fuse box, typically a 15A or 20A fuse. Check the fuse first if you’re troubleshooting—it’s even faster to inspect than the relay.
A blown fuse usually indicates a short circuit or an overloading fuel pump. If you replace the fuse and it blows again immediately, don’t just install a bigger fuse—that’s a fire hazard. Instead, inspect the wiring and the pump itself.
Where Else Could the Relay Be?
In rare cases, some Saab 9-3 models have a secondary fuse box in the engine compartment, near the battery, which also contains relays. However, the fuel pump relay on the 2006 model year is almost always in the interior fuse box. If you don’t find it there, check the engine bay box just to be thorough.
The Saab 9-3 also has a fuel pump control module (sometimes called a “fuel pump driver”) that lives near the fuel tank or under the rear seat on some models. This module controls the pump speed based on demand, and it can fail too. But for a 2006 model, the relay is the first component to suspect when the pump isn’t running.
Pro Tips for DIY Diagnosis
Here are a few extra pointers that can save you time and money:
- Listen carefully: Sit in the driver’s seat, close the door, and turn the key to “ON” (don’t crank the engine). If you hear a click from under the dash followed by a whir from the rear, both the relay and pump are working.
- Use a test light: If you have a 12V test light, you can probe the relay socket. With the key “ON,” one pin should have constant battery voltage. The relay then switches this power to the pump.
- Check ground connections: A corroded ground point near the battery or under the rear seat can cause the pump to run weak or not at all.
- Replace the relay preventively: If your 9-3 has over 100,000 miles and you’ve never replaced the relay, it’s a cheap $10–20 part worth swapping out proactively.
Why the Relay Fails and How to Extend Its Life
Relays fail because of normal wear and tear. The constant switching creates heat, and over the years, the contacts arc and oxidize. Vibration from the chassis also loosens internal connections. You can extend the life of your relay by:
- Keeping the fuse box clean and dry—moisture accelerates corrosion.
- Using dielectric grease on the relay terminals to prevent oxidation.
- Not overtightening any trim that presses against the fuse box, which can stress the relay socket.
