2007 Jeep Compass Fuel Pump Relay Location: A Practical Guide for Owners

The fuel pump relay on a 2007 Jeep Compass is located inside the engine compartment fuse box, which is technically called the Totally Integrated Power Module (TIPM). This black box sits on the driver's side of the engine bay, near the battery and behind the headlight assembly. Inside that module, the fuel pump relay is not labeled as a separate component on the fuse diagram; instead, the fuel pump circuit is controlled through the Auto Shut Down (ASD) relay. If your Compass cranks but will not start, and you suspect a fuel delivery problem, checking this relay should be your first step.

Many owners search for a dedicated "fuel pump relay" symbol on the fuse box cover and come up empty. That is because the 2007 Compass routes fuel pump power through the ASD relay, which also controls the ignition coils and fuel injectors. Understanding this setup saves you time and prevents unnecessary part replacement. This guide walks you through the exact location, how to test the relay, common failure symptoms, and what replacement parts you actually need.

Where the Fuse Box Is Located

The Integrated Power Module, which Jeep also calls the TIPM, is positioned in the engine compartment on the left side, close to the air cleaner assembly and the battery. The component locator in the factory service manual confirms that the fuse and relay block sits in the left front area of the engine bay. To open it, press the two plastic locking tabs on the sides of the cover and lift straight up. The underside of the cover has a printed diagram showing fuse numbers and amperage ratings, but it does not list every relay by name. For that, you need the full diagram from the owner's manual or a service guide.

The TIPM houses three types of components: mini-fuses, J-case fuses, and relays. Mini-fuses handle smaller loads like interior lights and the radio. J-case fuses are larger and manage high-amperage systems such as the radiator cooling fan. Relays sit in dedicated sockets and control higher-current circuits like the fuel pump, radiator fan, and starter. The 2007 model uses a relay layout that includes the ASD relay, radiator fan relays, and a hill descent relay mounted on the same block.

Understanding the Fuel Pump Relay Circuit

The fuel pump on the 2007 Jeep Compass does not have a stand-alone relay labeled "fuel pump." Instead, the powertrain control module (PCM) commands the ASD relay to close when you turn the ignition to the ON position. This sends power to several components at once, including the fuel pump, ignition coils, and fuel injectors. The wiring diagram for the 2.4L engine shows the fuel pump control output from the PCM going through the TIPM, with the ASD relay providing the main switching action.

The relay box layout for 2007 and 2008 models lists the Auto Shut Down relay in position R4. The radiator fan low/high relay is R1, the series/parallel relay is R3, and the medium/high relay is R5. The hill descent relay sits in R6. There is no separate fuel pump relay listed because the ASD relay covers that function.

This matters for troubleshooting. If the fuel pump is dead, the problem could be the ASD relay, the fuel pump itself, or the wiring between them. A quick way to narrow it down is to listen for the fuel pump prime when you turn the key to ON. You should hear a faint whirring sound from the rear of the vehicle for about two seconds. If you hear nothing, the relay may not be closing, or the pump may be receiving no power.

How to Test the ASD Relay

Before you replace anything, test the relay to confirm it is actually bad. Here is a step-by-step process that works for most DIY owners.

Step 1: Disconnect the battery. Always remove the negative battery cable before working near the TIPM. This prevents accidental shorts and protects the sensitive electronics inside the module.

Step 2: Remove the ASD relay. With the fuse box cover off, locate relay R4 in the relay block. Grasp it firmly and pull straight up. It should come out without excessive force. If it feels stuck, rock it gently side to side.

Step 3: Inspect the relay. Look for burn marks, melted plastic, or loose terminals. A relay that smells burnt or shows discoloration is almost certainly failed.

Step 4: Swap with a known-good relay. The radiator fan low/high relay (R1) and the ASD relay are typically the same part number. Swap the ASD relay with R1, then try starting the engine. If the vehicle starts, the original ASD relay was bad. If it still cranks without firing, the relay is likely fine, and the problem lies elsewhere.

Step 5: Use a multimeter for a definitive test. Check the coil resistance across the two control terminals. Most relays in this application read between 50 and 120 ohms. If you read infinite resistance, the coil is open and the relay is dead. You can also apply 12 volts to the coil terminals and listen for a click, which confirms the contacts are closing.

Common Symptoms of a Failing Fuel Pump Relay

A bad ASD relay can produce symptoms that mimic a dead fuel pump. Here are the most common signs to watch for.

1. Engine cranks but will not start. This is the classic symptom. The starter turns the engine over, but the fuel pump never primes, so there is no fuel pressure at the rail.

2. Intermittent stalling. The engine may run fine for a while, then suddenly die without warning. This happens when the relay contacts overheat and open the circuit. After a few minutes, it may start again.

3. No fuel pump prime noise. Turn the key to the ON position without cranking. You should hear a brief whirring sound from the fuel tank area. If you do not hear it, either the relay is not closing, the pump is dead, or there is a wiring issue.

4. Engine runs rough or hesitates under load. A relay with high resistance can drop voltage to the fuel pump, causing low fuel pressure. The engine may stumble during acceleration or at highway speeds.

5. Diagnostic trouble codes. If the PCM detects a loss of communication with the fuel pump circuit, it may store codes related to the fuel system or misfires. Reading the codes with a scanner can help narrow down the problem.

Keep in mind that a failing fuel pump itself produces similar symptoms. If the relay tests good, check fuel pressure with a gauge. The 2007 Compass should show around 55 to 60 psi with the key in the ON position. Low or zero pressure points to the pump or a clogged fuel filter.

Replacement Cost and Part Options

If you confirm the ASD relay is bad, replacement is cheap and easy. A genuine Mopar relay typically costs between $15 and $30 at a dealership or online parts retailer. Aftermarket relays are even less, usually in the $8 to $15 range. Labor is essentially zero if you do it yourself, since the relay simply unplugs and plugs back in.

If the fuel pump itself is the culprit, that is a different story. The fuel pump sits inside the fuel tank, and replacement is a moderately involved job. On the 2007 Compass, the pump is integrated into the fuel pump module, which also includes the sending unit and fuel level sensor. A new fuel pump module typically costs between $489 and $540 in parts, with labor adding another $596 to $660 at a shop. Total replacement cost usually lands between $1,053 and $1,200.

For a professional mobile mechanic, the fuel pump relay replacement service on a 2007 Compass runs about $139, with roughly $22 in parts and $95 in labor. Shop or dealer pricing may be higher, ranging from $160 to $200.

Step-by-Step: Accessing the Fuse Box Safely

If you have never opened the fuse box on your Compass, here is how to do it without damaging anything.

Step 1: Park on a level surface and turn off the engine. Remove the key from the ignition. Let the engine cool down if you have been driving, because components near the radiator can stay hot for a while.

Step 2: Open the hood. Pull the hood release lever inside the cabin, then lift the hood and secure it with the prop rod.

Step 3: Locate the TIPM. Look on the driver's side of the engine bay, near the battery. It is a black rectangular box with a plastic cover. If you have trouble spotting it, follow the positive battery cable; it usually runs directly into the TIPM.

Step 4: Remove the cover. Press the two locking tabs on the sides and lift straight up. Set the cover aside where it will not get dirty.

Step 5: Read the diagram. The underside of the cover shows the fuse layout with numbers and amperage ratings. The relay positions are also marked, though sometimes faintly. Use the full diagram from the owner's manual for a clearer view.

Step 6: Identify the relay. Refer to the relay box layout for 2007-2008 models, which lists the ASD relay as R4. If you have a later model year, the relay layout may differ slightly, so always check the diagram for your specific year.

Tips for Avoiding Common Mistakes

Working on the electrical system of any modern vehicle requires care. Here are a few practical tips to keep you safe and prevent unnecessary damage.

Always disconnect the battery before removing fuses or relays. This is not optional. The TIPM contains sensitive electronics that can be damaged by voltage spikes. Disconnecting the negative battery cable eliminates this risk.

Use a fuse puller instead of your fingers. Fuses can be tight, and pulling them with fingers can break the plastic housing. Most fuse boxes come with a small puller tool stored inside the cover. Use it for both fuses and relays.

Do not substitute a higher-amperage fuse or relay. If a fuse keeps blowing, there is an underlying short circuit. Installing a larger fuse to stop the blowing only creates a fire risk. Fix the short first.

Test before you replace. A relay that clicks when you apply power is not necessarily good. The contacts inside can still be worn or pitted. Always test the relay under load, or swap it with a known-good unit, before buying a replacement.

When to Call a Professional

While replacing the ASD relay is a simple DIY job, some situations call for professional help. If you have tested the relay and confirmed it is good, but the fuel pump still does not run, the problem may be in the wiring, the PCM, or the fuel pump itself. Diagnosing these issues requires a fuel pressure gauge, a multimeter, and sometimes a scan tool to read live data from the PCM.

Fuel pump replacement on the 2007 Compass involves dropping the fuel tank or cutting an access panel in the floor. Both approaches require special tools and care to avoid damaging the fuel lines and sending unit. If you are not comfortable working with fuel systems, take the vehicle to a qualified mechanic. The job typically takes two to three hours for a professional, and the peace of mind is worth the cost.

A mobile mechanic service can also handle the job at your home or office, which eliminates the need to tow the vehicle. Pricing for fuel pump relay replacement through such a service runs around $117 on average, with parts at $22 and labor at $95. For the fuel pump itself, expect a much higher bill, as outlined earlier.

Final Thoughts

The 2007 Jeep Compass fuel pump relay is the ASD relay, located in the Totally Integrated Power Module on the driver's side of the engine bay. It is a small, inexpensive component that can cause big problems when it fails. Testing it takes about ten minutes and requires no special tools beyond a multimeter or a simple relay swap. If the relay checks out, move on to the fuel pump itself, which sits inside the fuel tank and is a more involved repair.

Remember the key points: the fuel pump relay is actually the ASD relay in position R4 on the 2007-2008 relay block; listen for the fuel pump prime when you turn the key; test by swapping with the radiator fan relay; and always disconnect the battery before working on the TIPM.
