2009 Saturn Outlook Fuel Pump Relay Location: A Straightforward Owner’s Guide
The fuel pump relay on a 2009 Saturn Outlook is located in the engine compartment fuse box, which sits near the battery on the driver’s side of the vehicle. This relay is a small, black rectangular component that controls the electrical current to the fuel pump. If your Outlook cranks but will not start, or if you hear no hum from the fuel tank when you turn the key, the relay is one of the first things to check before you consider replacing the more expensive fuel pump itself.
In this guide, we will walk you through everything you need to know about the fuel pump relay on the 2009 Saturn Outlook. You will learn exactly where to find it, how to test it, how to replace it, and what symptoms point to a failing relay versus a failing fuel pump. We will also cover related fuses, common mistakes, and a practical recommendation for a reliable replacement fuel pump if you end up needing one.
What Does the Fuel Pump Relay Do?
Every time you turn the ignition key to the "ON" position, the fuel pump relay activates. It sends battery voltage to the electric fuel pump located inside the fuel tank, which pressurizes the fuel system so the engine can start. Once the engine is running, the relay continues to supply power as long as the engine control module (ECM) keeps the circuit closed.
The relay is essentially a heavy-duty switch controlled by a low-current signal from the ECM. When the relay fails, the fuel pump receives no power, and the engine will crank over but will not start. Because the relay is much cheaper and easier to replace than the fuel pump itself, it is always wise to test the relay first when you suspect a fuel delivery problem.
The 2009 Saturn Outlook uses a turbine-style electric fuel pump located inside the modular fuel sender assembly in the fuel tank. The pump is controlled by the fuel pump flow control module (FPCM), which receives a desired fuel pressure message from the ECM. The relay supplies the main power feed to this system, so if the relay is faulty, the entire fuel delivery system is dead.
Where Is the Fuel Pump Relay Located?
The fuel pump relay is located in the engine compartment fuse box. On the 2009 Saturn Outlook, this fuse box is positioned near the battery on the driver’s side of the engine bay. It is a large black plastic box with a removable lid. Open the hood and look toward the driver’s side fender; you will see the fuse box mounted close to the battery.
To access the relay, follow these simple steps:
- Open the hood and prop it securely.
- Locate the engine compartment fuse box near the battery on the driver’s side.
- Press the tabs on the lid and lift it off. The underside of the lid usually has a diagram that labels the fuses and relays.
- Find the relay labeled "FUEL PUMP" in the fuse box layout. On the 2009 Outlook, this relay is clearly marked.
The passenger compartment fuse box, located under the instrument panel on the passenger side, does not contain the fuel pump relay. So do not waste time looking there.
How to Test the Fuel Pump Relay
Before you buy any parts, spend five minutes testing the relay. A relay that has failed internally will not pass voltage to the fuel pump, but the relay itself is easy to check with a multimeter.
Step-by-step relay test:
- Turn the ignition off and remove the fuel pump relay from the engine compartment fuse box.
- Look at the relay terminals. You should see four or five metal prongs on the bottom.
- Set your multimeter to measure resistance (ohms).
- Touch the meter leads to the coil terminals (usually terminals 85 and 86). You should see a resistance reading between 50 and 120 ohms. If the reading is infinite (open circuit), the relay coil is burned out and the relay needs replacement.
- Apply 12 volts to terminals 85 and 86 using a small battery or power probe. You should hear a distinct "click" as the internal switch closes.
- While voltage is applied, check continuity between terminals 30 and 87. With power applied, you should see near-zero resistance (closed circuit). Without power, you should see infinite resistance (open circuit).
If the relay fails any of these checks, replace it. A relay that clicks but does not close the contacts will still cause a no-start condition.
Symptoms of a Bad Fuel Pump Relay
A failing fuel pump relay on a 2009 Saturn Outlook will show specific symptoms. Recognizing these early can save you time and money.
Common signs of a bad relay:
- Engine cranks but will not start. This is the classic symptom. You turn the key, the starter motor spins, but the engine never fires because no fuel pressure is built up.
- No fuel pump prime sound. When you turn the ignition to "ON" (without cranking), you should hear a brief whirring noise from the fuel tank area. If you hear nothing, the relay is likely not sending power to the pump.
- Intermittent stalling. If the relay contacts are worn, the engine may run for a while and then suddenly die. After a few minutes, it may restart. This is often mistaken for a failing fuel pump.
- Engine runs rough or hesitates. A relay that is failing under load can cause a voltage drop to the fuel pump, leading to low fuel pressure and poor engine performance.
If you experience any of these symptoms, test the relay first. A new relay costs about $23 in parts plus labor if you have it installed by a shop, which is far cheaper than replacing a fuel pump.
How to Replace the Fuel Pump Relay
Replacing the fuel pump relay is a simple task that takes about five minutes. No special tools are required.
Follow these steps:
- Ensure the ignition is off and the keys are removed.
- Open the hood and remove the engine compartment fuse box cover.
- Locate the fuel pump relay using the diagram on the underside of the cover.
- Pull the relay straight out. It is held by friction; a firm tug will release it.
- Compare the new relay to the old one. The terminal layout must match. Most relays look identical, but confirm the part number on the side.
- Push the new relay firmly into the socket until it seats completely.
- Replace the fuse box cover and close the hood.
- Turn the ignition to "ON" and listen for the fuel pump prime sound. If you hear it, the relay is working.
Do not use a relay from another circuit unless you are certain it has the same amperage rating. Using an undersized relay can cause overheating and electrical fires.
The Fuel Pump Fuse: A Related Check
While you are working in the engine compartment fuse box, it is also worth checking the fuel pump fuse. On the 2009 Saturn Outlook, the fuel pump circuit is protected by a fuse in the same fuse box. A blown fuse will mimic a failed relay, causing the same no-start condition.
The engine compartment fuse box on the Outlook includes a dedicated "FUEL PUMP" fuse. Pull it out and inspect the metal strip inside. If the strip is broken or melted, replace the fuse with one of the same amperage. Never use a higher-rated fuse, as this can damage the fuel pump or wiring.
If the fuse blows again immediately after replacement, you likely have a short circuit in the fuel pump wiring. In that case, professional diagnosis is recommended.
Fuel Pump Relay vs. Fuel Pump: How to Tell the Difference
One of the most common mistakes owners make is replacing the fuel pump when the relay is at fault. The fuel pump on the 2009 Saturn Outlook is inside the fuel tank, and replacing it is an expensive and labor-intensive job. The average cost for a fuel pump replacement on this vehicle is between $1,445 and $2,329, with parts alone costing up to $2,007. Compare that to a relay replacement that costs around $141 including labor.
Before you commit to a fuel pump replacement, confirm the relay is good. Here is a simple diagnostic sequence:
- Check the relay as described above.
- Check the fuse for continuity.
- Listen for the pump prime when turning the key to "ON."
- If you have no prime sound, check for voltage at the fuel pump connector. You can access the fuel pump electrical connector near the fuel tank.
- If voltage is present but no pump sound, the fuel pump itself is likely faulty.
Most no-start conditions caused by fuel delivery issues trace back to either the relay, the fuse, or the fuel pump itself. Testing the relay first is the smartest and cheapest move.

Frequently Asked Questions
Q: How do I know if my fuel pump relay is bad?
A: If the engine cranks but will not start, and you hear no fuel pump prime sound, the relay is a likely culprit. Remove the relay and test it with a multimeter. Check for coil resistance between 50 and 120 ohms and confirm the contacts close when power is applied.
Q: Can a bad fuel pump relay cause intermittent stalling?
A: Yes. Worn relay contacts can lose connection under load, causing the engine to stall suddenly. After the relay cools or the contacts shift, the engine may restart. This is a classic symptom of a failing relay.
Q: Is the fuel pump relay in the cabin fuse box?
A: No. On the 2009 Saturn Outlook, the fuel pump relay is in the engine compartment fuse box, which is located near the battery on the driver’s side. The passenger compartment fuse box under the instrument panel does not contain the fuel pump relay.
Q: How much does it cost to replace the fuel pump relay?
A: Expect to pay around $141 for a professional replacement, which includes about $23 for parts and $95 for labor. If you do it yourself, the relay costs around $20 to $30.
Q: What should I do if the new relay does not fix the problem?
A: Check the fuel pump fuse. If the fuse is intact, test for voltage at the fuel pump connector. If voltage is present but the pump does not run, the fuel pump assembly itself needs replacement.
