07 PT Cruiser Fuel Pump Relay Location: The Complete Guide to Finding and Testing It


If your 2007 PT Cruiser cranks but won’t start, or if it stalls unexpectedly while driving, the fuel pump relay is often the first thing to check. The fuel pump relay on a 2007 PT Cruiser is located inside the Totally Integrated Power Module (TIPM), which is the main fuse and relay box in the engine bay. This box sits on the driver’s side, right next to the air cleaner assembly. The relay itself is usually labeled as "FUEL PUMP" or "FP" on the diagram found on the underside of the TIPM cover. Knowing this location saves you time and prevents you from pulling apart the interior or chasing down the wrong parts.

Where Exactly Is the TIPM and How Do You Access It?

The 2007 PT Cruiser uses a centralized electrical system known as the Totally Integrated Power Module (TIPM). This unit handles all the major relays and fuses for the vehicle. It is located under the hood, on the driver’s side, near the battery and the air filter housing .

  1. Open the Hood: Make sure the engine is off and the keys are out of the ignition.
  2. Locate the Box: Look for a large, black rectangular box (the TIPM) on the driver’s side of the engine bay. It sits just behind the battery and next to the air cleaner.
  3. Remove the Cover: The cover has two clips on the sides. Press them in and lift the cover straight up.
  4. Check the Diagram: Flip the cover over. On the underside, there is a clear diagram that labels every relay and fuse. The fuel pump relay is typically labeled "FUEL PUMP" .

If the diagram is worn or hard to read, you can also look for a relay labeled "FP" in the relay cluster. It is often located in the upper-left or lower-right corner of the relay section .

How to Identify the Correct Relay

Once you have the cover off, you will see a grid of relays and fuses. The fuel pump relay is a square, plastic module that is larger than the standard blade fuses. It typically has four or five metal pins on the bottom .

  • Labeling: In the 2001-2005 PT Cruiser models, the Power Distribution Center (PDC) clearly labels the relay as "R3" for the Fuel Pump . For the 2006-2010 models (including the 2007), the TIPM cover uses text labels. Look for the word "FUEL" or "FUEL PUMP" .
  • Visual Check: The relay is often a standard color, such as black or dark blue. You can compare its size to other relays in the box to help confirm it.
  • TIPM Troubleshooting: Keep in mind that the TIPM itself is a known failure point on Chrysler products of this era. If you are having intermittent electrical issues that go beyond just the fuel pump, the TIPM might be the root cause .

How to Test the Fuel Pump Relay Before Replacing It

Before you buy a new relay, it is smart to test the old one. This will confirm whether the relay is the problem or if the issue is deeper in the wiring or the fuel pump itself.

Step 1: Visual and Physical Inspection

  • Remove the relay by pulling it straight out. You can use a relay puller tool or a flathead screwdriver, but be careful not to bend the metal pins .
  • Take a photo of the relay layout before removing anything. This is a practical tip that helps you put everything back correctly .

Step 2: Use a Multimeter

  • Check the Coil: Set your multimeter to the resistance (ohms) setting. Place the probes on terminals 85 and 86 of the relay. A good relay should show a resistance reading between 70 and 80 ohms . If you get infinite resistance (OL), the coil inside is broken.
  • Check the Switch: With the relay still unpowered, check terminals 30 and 87A. You should see continuity (very low resistance) because this is the normally closed circuit .

Step 3: Apply Power to Test (The "Click" Test)

  • Get a 12V battery source (like a car battery or a jump box).
  • Connect a jumper wire from the positive terminal to relay terminal 85.
  • Touch a jumper wire from the negative terminal to relay terminal 86.
  • If the relay is good, you will hear a distinct "click." This means the electromagnetic coil is working.
  • While the relay is energized, check terminals 30 and 87. You should now see continuity (low resistance). This confirms the main power contacts are closing properly .

Common Symptoms of a Bad Fuel Pump Relay

If your relay fails the test, or if you are experiencing these symptoms, it is time for a replacement:

  1. Engine Cranks but Does Not Start: The most common symptom. The starter turns the engine over, but the fuel pump never gets the signal to run .
  2. No Fuel Pressure: You can verify this by checking the Schrader valve on the fuel rail. If there is no pressure when you turn the key to the "ON" position, the relay might be dead .
  3. Stalling: The engine starts fine but then randomly dies while driving. This happens when the relay contacts get hot and fail, cutting power to the pump .
  4. Silent Fuel Pump: When you turn the key to the "ON" position, you should hear a quiet whirring sound from the rear of the car for about 1-2 seconds. If you don't hear it, the relay or the pump is not getting power.

A Note on the ASD Relay

Many owners confuse the fuel pump relay with the Automatic Shut Down (ASD) relay. In the 2007 PT Cruiser, the ASD relay is also located in the TIPM. The ASD relay is a separate piece that controls power to the ignition coils and fuel injectors, not just the fuel pump . If your car starts with starting fluid but dies, your fuel pump relay is likely fine, but the ASD relay or the pump itself could be the issue . The diagram on the TIPM cover will help you distinguish between the two, as they are often different sizes or labeled differently.
