2006 Saab 9-3 Fuel Pump Relay: Location, Symptoms, and Replacement Guide

If your 2006 Saab 9-3 is cranking but won't start, the fuel pump relay is one of the first things you should check. This small, inexpensive component is a common failure point on the 9-3, and it can leave you stranded without warning. The good news is that replacing it is a straightforward DIY job that takes about 15 minutes and costs between $15 and $55 for the part . Before you spend hundreds of dollars on a new fuel pump, take the time to test the relay first—many owners have replaced a perfectly good pump only to discover the real issue was a $15 relay .

The 2006 Saab 9-3 fuel pump relay is located behind the trim panel on the driver's side, near the A-pillar and your left foot . It is not listed in the owner's manual fuse diagrams, which is why so many owners miss it during troubleshooting . This guide walks you through everything you need to know: where the relay is, what symptoms indicate a failing relay, how to test it, and how to replace it yourself.


Why the Fuel Pump Relay Matters

The fuel pump relay controls power delivery to the fuel pump. When you turn the ignition key to the "ON" position, the relay closes and sends 12 volts to the fuel pump, which then primes the fuel system for about two seconds . If the relay fails, the pump never receives power, the fuel rail stays dry, and the engine won't start .

The 2006 Saab 9-3 uses a standard automotive relay with a 5-pin configuration. The same relay is used for several other circuits in the car, which makes testing by swapping very easy . The relay itself is inexpensive, but a failed relay can mimic the symptoms of a much more serious and costly problem, like a dead fuel pump .


Symptoms of a Failing Fuel Pump Relay

A bad fuel pump relay usually shows some warning signs before it fails completely. Here are the most common symptoms you might notice:

  1. Engine cranks but won't start. This is the most obvious symptom. The starter motor turns the engine over, but there is no fuel pressure, so the engine never fires .

  2. No fuel pump priming sound. When you turn the ignition to "ON" (without starting the engine), you should hear a brief humming or whirring sound coming from the rear of the car near the fuel tank. If you hear nothing, the pump is not receiving power .

  3. Intermittent starting issues. If the relay is failing but not completely dead, you may experience intermittent no-start conditions. The car might start fine one day and refuse to start the next. This happens because the relay contacts become worn or corroded over time .

  4. Engine stalls while driving. In some cases, a failing relay can cause the engine to lose power and stall while you are driving. This is dangerous and should be addressed immediately .

  5. Melted or burned relay socket. In one documented case, the relay socket itself melted due to high resistance at the relay contacts. This is a sign of excessive heat and a failing relay .

If you experience any of these symptoms, the relay should be your first suspect—especially if the car cranks strongly but there is no fuel pressure at the fuel rail .


Where Is the Fuel Pump Relay Located?

On the 2006 Saab 9-3, the fuel pump relay is not in the main fuse boxes. It is hidden behind the trim panel on the driver's side footwell, near the A-pillar. Here is how to access it:

  1. Open the driver's door and look at the side of the dashboard near your left foot.
  2. Remove the kick panel (the trim piece covering the side of the footwell). It is held in place by a few clips or screws. In some cases, you may need a 10mm socket to remove a bolt securing the panel .
  3. Locate the relay. You will see a small relay mounted vertically or horizontally in a socket. It is labeled as relay 102 in the factory wiring diagrams .

On the 2.8L Turbo V6 engine (which is in the 9-3 Aero model), the relay is in the same location—behind the right kick panel (which is the passenger side in left-hand-drive markets) . Some sources describe it as "front right side of the vehicle" . The exact wording can be confusing because "right" depends on your perspective. In a left-hand-drive car, the driver is on the left, so the right kick panel is on the passenger side. However, the relay for the fuel pump on the 2.8L is listed as being behind the left kick panel in the wiring diagrams . Always verify by looking at both sides if you are unsure.

The relay is not in the owner's manual fuse charts, which only list the fuses and relays in the main electrical centers . This is a common source of confusion for DIY owners, so do not waste time looking for it in the manual.


How to Test the Fuel Pump Relay

There are two reliable ways to test the relay: the swap test and the multimeter test. Start with the swap test because it is faster and requires no special tools.

Method 1: The Swap Test

  1. Turn the ignition off and remove the key.
  2. Remove the fuel pump relay from its socket.
  3. Find an identical relay in the engine bay fuse box. The windshield wiper relay (R9 in the engine bay fuse box) or the horn relay (R6) are good candidates—they use the same 5-pin configuration .
  4. Install the known-good relay into the fuel pump relay socket.
  5. Turn the ignition to "ON" and listen for the fuel pump priming sound from the rear of the car.
  6. If you hear the pump buzz, the original relay was faulty .

This test works because relays are interchangeable as long as the part number and pin layout are identical . The windshield wiper relay from a 2006 Saab 9-3 worked perfectly as a temporary fix in one documented case .

Method 2: The Multimeter Test

If you have a digital multimeter, you can test the relay directly:

  1. Remove the relay from the socket.
  2. Set your multimeter to ohms (resistance) mode.
  3. Measure across the coil terminals (pins 85 and 86). You should see a resistance value typically between 50 and 120 ohms. If you see infinite resistance, the coil is open and the relay is dead .
  4. Apply 12 volts to pins 85 and 86. You should hear a click as the relay energizes.
  5. Check the switch contacts (pins 30 and 87). With the relay energized, you should read zero ohms across these pins, indicating the contacts are closed .

If the relay fails any of these tests, replace it.


How to Replace the Fuel Pump Relay

Replacing the relay is a simple process that requires only basic tools. Follow these steps:

  1. Gather your tools. You will need a 10mm socket (for the kick panel bolt), a screwdriver or trim tool, and the replacement relay. The OEM relay part number is 32-101-476-M14, available for about $15 .
  2. Disconnect the negative battery cable. This is a safety precaution to prevent accidental shorts while you are working in the footwell.
  3. Remove the kick panel as described in the location section above.
  4. Pull the old relay straight out of its socket. It may require a firm tug.
  5. Inspect the socket. Look for signs of melting, corrosion, or burnt contacts. If the socket is damaged, you may need to replace the socket itself. These are available on eBay for around $8 .
  6. Install the new relay by pushing it straight into the socket until it clicks into place.
  7. Reinstall the kick panel and secure it with the bolt or clips.
  8. Reconnect the battery and test the system by turning the ignition to "ON." Listen for the fuel pump priming sound.

The entire job takes about 15 minutes. Replacement relays cost between $17 for aftermarket and $55 for OEM .


Where Are the Other Fuses and Relays?

The 2006 Saab 9-3 has three main electrical centers where fuses and relays are grouped :

  1. Engine compartment (Fuse Box No. 1): Located between the front bumper and the battery. This box contains fuses for the engine control module, fuel injectors, ignition coils, and the main relay .

  2. Engine compartment (Fuse Box No. 2): Located adjacent to the battery beneath a protective cover. This is the main Underhood Electrical Center (UEC) and contains relays for the horn, wipers, starter motor, and headlamp flash-to-pass .

  3. Trunk rear electrical center: Located behind the left-side panel in the trunk. This center handles rear lighting, trailer connections, and some convertible-specific functions .

For the 2006 model year, the fuse for the fuel pump (fuse No. 2, rated at 20A) is in the fuse panel in front of the battery . This fuse also protects the preheated oxygen sensors (lambda probes) .


Common Mistakes When Diagnosing a No-Start Condition

Many owners make the mistake of replacing the fuel pump before checking the relay. This is understandable because the symptoms are identical, but it is also expensive. One owner reported replacing the entire fuel pump, only to discover the real issue was a melted relay socket . Here are the most common diagnostic mistakes:

  1. Skipping the relay check. Always test the relay first. It takes five minutes and costs nothing if you use the swap test .
  2. Checking the wrong fuse box. The fuel pump relay is not in the main fuse boxes under the hood. It is in the driver's footwell .
  3. Ignoring melted sockets. If the relay contacts were loose or corroded, the socket may be damaged. Replacing only the relay without checking the socket can lead to a recurrence .
  4. Not listening for the pump. Turn the key to "ON" and listen. If you hear a hum from the rear, the pump is receiving power, and the relay is probably fine .

Is There a Recall for the Fuel Pump Relay?

No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any recalls or technical service bulletins (TSBs) for relay failures on the 2004-2011 Saab 9-3 . Recalls for this vehicle range were issued for other items like seat belt retractors and airbags, but not for the relay system .


Relays Are Cheap — Carry a Spare

Because relays are inexpensive and a failure can leave you stranded, many Saab owners buy a spare relay to keep in their glove box . This allows for a quick roadside diagnosis and fix by simply swapping the suspect relay with a new one . A replacement relay costs between $17 and $55, depending on whether you choose aftermarket or OEM . Shop labor, if you choose to have a mechanic do the replacement, adds $50 to $100 .

Even if you are not currently experiencing problems, carrying a spare relay is a smart idea for any 9-3 owner. If you find yourself stranded, you can pull over, swap in the spare, and be back on the road in a few minutes.


What If the Relay Is Fine?

If the relay tests good and the fuse is not blown, the problem may be elsewhere. Check for these issues:

  1. Fuel pump failure. If the relay clicks and you have 12 volts at the pump connector, the pump itself may be dead. You can verify power at the tank connector using a multimeter .
  2. Fuel pump control module. On some models, a separate control module regulates fuel pump speed. This module can fail independently .
  3. Wiring issues. Broken wires or corroded connectors between the relay and the fuel pump can interrupt power delivery .
  4. Crankshaft position sensor. If the engine computer does not receive a crank signal, it will not energize the fuel pump relay. This sensor failure can cause a no-start condition that feels like a fuel issue .

A fuel pressure gauge can help you determine if the pump is delivering fuel. Connect it to the Schrader valve on the fuel rail and check the pressure with the ignition "ON" . If the pressure does not match the manufacturer's specification, the pump may be failing .


The Bottom Line

The 2006 Saab 9-3 fuel pump relay is a small component with a big responsibility. When it fails, your car will not start, and the symptoms can easily be mistaken for a dead fuel pump . The relay is hidden behind the driver's side kick panel near the A-pillar, not in the owner's manual fuse charts . Before spending hundreds of dollars on a new pump, test the relay by swapping it with a known-good unit from another circuit .

Replacement is a true DIY job. With a 10mm socket and a few minutes of work, you can have the new relay installed and be back on the road . The part itself costs between $17 and $55, and many owners keep a spare in the glove box for emergencies .

Remember the golden rule of Saab 9-3 diagnostics: when the engine cranks but won't start, check the fuel pump relay before you order a new fuel pump . It could save you a lot of time and money.
