06 PT Cruiser Fuel Pump Relay Location: A Complete Guide to Finding and Replacing It

If your 2006 PT Cruiser is cranking but not starting, stalling while driving, or the fuel pump isn't making its usual priming noise when you turn the key, the fuel pump relay is a likely culprit. The fuel pump relay on a 2006 PT Cruiser is located inside the Totally Integrated Power Module (TIPM), which is the main fuse and relay box under the hood near the battery. This relay controls the power supply to the fuel pump, and when it fails, the pump won't receive power, leaving your engine without fuel. Before you assume the fuel pump itself is bad, testing and replacing this relay is a simple, low-cost fix that can save you hundreds of dollars.

Understanding the Fuel Pump Relay and Its Role

The fuel pump relay acts as an electrical switch. When you turn the ignition key to the "ON" position, the relay closes and sends power from the battery to the fuel pump, pressurizing the fuel system. Once the engine starts, the relay stays closed to keep the pump running. If the relay fails, the fuel pump never gets the signal to turn on, which means no fuel reaches the engine.

On the 2006 PT Cruiser, this relay is not a standalone component you can easily spot. It is integrated into the TIPM, a large black box located in the engine bay on the driver's side, near the air cleaner assembly. This design is different from earlier PT Cruiser models (2001-2005), which had a separate Power Distribution Center (PDC) with a clearly labeled fuel pump relay.

Symptoms of a Faulty Fuel Pump Relay

How do you know if the relay is the problem? Here are the most common signs:

  1. Engine cranks but won't start: The starter motor turns the engine over, but the engine never fires up. You may not hear the fuel pump hum when you turn the key to "ON."
  2. Intermittent stalling: The engine may start and run fine for a while, then suddenly die while driving, especially under load or during acceleration.
  3. No priming noise: When you turn the ignition key to the "ON" position (without starting), you should hear a brief whirring sound from the rear of the car for about 2-3 seconds. If you don't hear this, the fuel pump is not getting power.
  4. Sputtering or hesitation: If the relay is failing intermittently, the fuel pump may lose power momentarily, causing the engine to sputter or hesitate during acceleration.

How to Locate the Fuel Pump Relay in a 2006 PT Cruiser

Finding the relay on a 2006 model is a bit trickier than on older models. Here's a step-by-step approach:

Step 1: Open the hood and find the TIPM. The Totally Integrated Power Module is a black plastic box located on the driver's side of the engine bay, right next to the air cleaner housing and near the battery. It's about the size of a shoebox and has a removable cover.

Step 2: Remove the TIPM cover. The cover is usually held on by two clips or a small screw. Lift it off to expose the array of fuses and relays inside.

Step 3: Look for the relay diagram. The underside of the TIPM cover has a diagram that labels the position of each fuse and relay. The fuel pump relay is typically labeled as "Fuel Pump" or "FP," or you may see it listed as relay #14 in some diagrams.

Step 4: Identify the relay visually. The fuel pump relay is a small, rectangular black or gray module with electrical terminals. On the 2006 model, it is often located in the rear section of the TIPM, closer to the firewall. Some sources mention that the relay is also found among the relays on the firewall itself, on the driver's side below the windshield.

Important note: If the diagram on the cover is missing or faded, you can find a copy of the fuse box diagram in your owner's manual or by searching online for "2006 PT Cruiser TIPM diagram."

How to Test the Fuel Pump Relay

Before you buy a new relay, test the old one to confirm it's bad. There are two simple ways to do this:

Method 1: The Swap Test. This is the easiest method. Find another relay in the TIPM that has the same part number and rating. Common relays to swap with include the horn relay or the starter relay. Remove the suspected fuel pump relay and swap it with a known good relay from a different slot. If the fuel pump starts working, you've found the problem.

Method 2: Listen for a Click. Have a helper turn the ignition key to the "ON" position while you listen near the TIPM. You should hear a distinct "click" from the relay when it engages. If you don't hear a click, the relay is likely not receiving power or is faulty.

Method 3: Use a Multimeter. If you want to be thorough, you can test the relay with a multimeter. With the relay removed, check for continuity between the coil terminals. The resistance should typically be between 50 and 120 ohms, depending on the specific relay. A reading of "OL" (open line) means the coil is burnt out.

Replacing the Fuel Pump Relay

Replacing the relay is a straightforward job that requires no special tools.

  1. Disconnect the battery. Always disconnect the negative battery cable before working on any electrical components to prevent short circuits.
  2. Remove the old relay. Grasp the relay firmly and pull it straight out of its socket. You may need a relay puller or a pair of needle-nose pliers, but usually, you can do it by hand.
  3. Install the new relay. Push the new relay into the same socket until it clicks into place securely. Make sure it is fully seated.
  4. Reconnect the battery. Reconnect the negative battery cable.
  5. Test the system. Turn the ignition key to the "ON" position and listen for the fuel pump priming noise. If you hear it, the repair was successful.

Common Issues with the 2006 PT Cruiser Fuel Pump Relay System

Beyond a simple relay failure, there are a few other things to keep in mind when troubleshooting your fuel system:

  • Corrosion in the TIPM: Moisture can get into the TIPM and cause corrosion on the relay terminals or the socket. If you see rust or green buildup, clean the terminals with electrical contact cleaner and apply dielectric grease before installing a new relay.
  • Blown Fuse: The fuel pump circuit also has a fuse. In the 2006 PT Cruiser, the fuel pump fuse is often a 20A mini fuse located in the TIPM. Check this fuse first before replacing the relay, as a blown fuse can cause the same symptoms.
  • TIPM Failure: On some 2006-2010 PT Cruisers, the entire TIPM can fail. This is a more serious issue where the module itself has internal faults, and it may need to be replaced entirely. If swapping the relay and checking the fuse doesn't fix the problem, the TIPM might be the root cause.

Why Choosing a Quality Fuel Pump Matters

If you've tested the relay and the fuse, and everything checks out, the problem may be the fuel pump itself. Replacing the fuel pump on a PT Cruiser is a much bigger job—it requires dropping the fuel tank. When you do need a new fuel pump, you want a part that is reliable, durable, and backed by a solid warranty.
