2006 PT Cruiser Fuel Pump Fuse Location: A Complete Guide for DIY Owners

If you drive a 2006 Chrysler PT Cruiser and the engine cranks but won't start, or if it stalls suddenly while driving, the fuel pump fuse is one of the first things you should check. The fuel pump fuse on a 2006 PT Cruiser is located in the Integrated Power Module (IPM), which sits under the hood on the driver's side, near the battery. It is a 20-amp fuse, and in most model configurations, it is labeled as fuse number 18. This guide walks you through the exact location, how to inspect and replace the fuse, and what to do if the fuse keeps blowing.

Understanding the PT Cruiser's Electrical Layout

The 2006 PT Cruiser uses a centralized fuse box called the Integrated Power Module (IPM). Unlike older vehicles that had separate fuse boxes for the interior and engine bay, the PT Cruiser consolidates most of its high-current fuses and relays into this single module under the hood . This module controls everything from the cooling fan to the fuel pump, and it is the first place you should look when dealing with fuel delivery issues.

The IPM is a black plastic box with a removable cover. On the underside of the cover, you will find a diagram that identifies what each fuse and relay controls. However, many owners report that this diagram is difficult to read or has faded over time, so it is helpful to know the layout in advance.

Locating the Integrated Power Module

Open the hood and look to the driver's side of the engine bay. The IPM is positioned directly next to the battery, mounted on the fender. It is a rectangular black box with a sturdy latch on the front. Press the latch and lift the cover straight up to access the fuses inside .

Once the cover is off, you will see an array of fuses and relays. The fuel pump fuse is a standard blade-type fuse. In the 2006 model year, the fuel pump fuse is rated at 20 amps . The exact position can vary slightly depending on the trim level and options, but it is almost always in the lower section of the IPM.

Identifying the Correct Fuse

Look for a fuse labeled with the number 18. This is the fuse that protects the fuel pump circuit . The fuse will be a small, rectangular plastic piece with two metal prongs. The plastic housing is typically colored to indicate its amperage rating. A 20-amp fuse is usually yellow, though some aftermarket fuses use different colors, so do not rely on color alone.

If you cannot find the number 18 on the diagram, trace the label. The cover diagram shows the fuse number and its corresponding circuit name. Look for "FUEL PUMP" or "FP" on the diagram. Some diagrams may abbreviate the label, so keep that in mind.

How to Test the Fuel Pump Fuse

Before replacing anything, you need to confirm the fuse is actually blown. Here is a simple step-by-step process:

  1. Turn off the ignition and remove the key. Safety first. You are working with electrical components, so the car should be completely off.
  2. Remove the fuse. Use a fuse puller tool, which is usually clipped inside the IPM cover, or a pair of needle-nose pliers. Grip the fuse firmly and pull it straight out.
  3. Inspect the fuse visually. Hold it up to a light source. A good fuse has a continuous metal strip visible through the clear plastic. If the strip is broken or melted, or if there are burn marks on the plastic, the fuse is blown.
  4. Use a multimeter (optional). If the fuse looks fine but you want to be certain, set your multimeter to the continuity or ohms setting. Touch one probe to each metal prong. A reading of zero or near zero indicates the fuse is good. A reading of infinite resistance means the fuse is blown.

The fuel pump fuse on a 2006 PT Cruiser is dedicated to the fuel pump circuit, but it also protects the fuel pump relay and related wiring . If this fuse is blown, the fuel pump will not receive power, which means no fuel pressure, and the engine will crank but fail to start.

Replacing the Fuel Pump Fuse

Replacing the fuse is a five-minute job that requires no special skills. Here is what to do:

  1. Purchase the correct replacement. You need a 20-amp blade-type fuse. These are available at any auto parts store, and they cost only a few dollars.
  2. Insert the new fuse. Align the two metal prongs with the slots in the fuse box. Push down firmly until the fuse seats fully. You should feel a slight click.
  3. Test the system. Turn the ignition to the "ON" position without starting the engine. You should hear the fuel pump prime for a second or two. The sound is a faint whirring noise coming from the rear of the car, near the fuel tank.
  4. Start the engine. If the engine starts and runs, the fuse replacement solved the problem.

It is that straightforward. However, if the new fuse blows immediately or shortly after installation, you have a deeper issue, which is covered below.

Why Does the Fuel Pump Fuse Keep Blowing?

A blown fuel pump fuse is rarely a one-time event. If the fuse fails repeatedly, something is drawing too much current. Here are the most common causes, listed from simplest to most complex:

  1. A failing fuel pump. The fuel pump motor draws more current as it wears out. Bearings wear, the armature drags, and the pump works harder to maintain pressure. This increased current draw eventually exceeds the fuse rating, causing it to blow. This is the most common reason for a recurring blown fuse .
  2. A short circuit in the wiring. The fuel pump wiring runs from the IPM, through the body, and to the fuel pump assembly at the rear of the car. If the insulation on this wiring rubs against the chassis and wears through, it can short to ground. This will blow the fuse instantly.
  3. A clogged fuel filter. A severely restricted fuel filter forces the pump to work against high resistance. This increases the electrical load and can cause the fuse to blow. While this is less common than a pump failure, it is worth checking.
  4. A faulty fuel pump relay. The relay itself can develop internal issues, though this typically causes a no-power condition rather than a blown fuse.

If the fuse blows more than once, do not simply keep replacing it. You need to diagnose the root cause. Continuing to install new fuses without addressing the underlying problem can lead to a complete fuel pump failure or even a wiring fire.

Other Fuel System Components to Check

The fuse is only one part of the fuel delivery system. If the fuse is good but the engine still will not start, check these components in order:

The fuel pump relay. The relay is located in the same IPM. It is a small black cube, often labeled "FUEL PUMP" or "FP." You can test the relay by swapping it with an identical relay in the box, such as the one for the horn or the headlights. If the engine starts with the swapped relay, the original relay is faulty.

The fuel pump itself. If the relay is good and the fuse is good, the pump may be dead. You can listen for the prime sound when turning the ignition to "ON." If there is no sound, the pump is likely not receiving power or has failed internally .

The inertia switch. Some PT Cruiser models have an inertia switch that cuts power to the fuel pump in the event of a collision. This switch is typically located in the passenger footwell or behind the kick panel. If it has been tripped, reset it by pressing the button on top.

The 2006 PT Cruiser Fuse Box Layout at a Glance

The Integrated Power Module contains dozens of fuses and relays. For quick reference, here are the key fuses you might need, based on the standard 2006 layout :

  1. Fuel Pump Fuse (No. 18) – 20 amps, protects the fuel pump and its relay.
  2. Ignition Run/Start Fuse (No. 10) – 40 amps, powers the ignition switch.
  3. Radiator Fan Fuse (No. 30) – 30 amps, controls the cooling fan.
  4. Powertrain Control Module Fuse (No. 9) – 20 amps, protects the engine computer.
  5. Auto Shutdown Relay (ASD) – This relay powers the fuel injectors and ignition coils.

The ASD relay is important. If it fails, you will lose spark and fuel simultaneously, and the engine will not start. It is located in the IPM and is often labeled "ASD" or "Auto Shutdown."

Preventing Future Fuel Pump Issues

Regular maintenance goes a long way. Here are a few practical tips to keep your fuel system healthy:

  • Replace the fuel filter every 30,000 miles. A clean filter reduces strain on the pump .
  • Keep the fuel tank at least a quarter full. Running on empty regularly causes the pump to overheat, because it relies on the fuel in the tank for cooling and lubrication.
  • Listen for unusual noises. A whining fuel pump is an early warning sign. If you hear a high-pitched hum from the rear of the car, have the pump tested before it fails completely.
  • Use quality fuel. Poor-quality fuel can leave deposits that clog the pump inlet strainer.

What to Do If the Problem Persists

If you have replaced the fuse, checked the relay, and confirmed the pump is receiving power but the engine still will not start, the issue may be mechanical. The fuel pump may be running but not building enough pressure. This can happen if the pump's internal check valve fails or if the fuel pressure regulator is leaking. At this point, you will need a fuel pressure gauge to test the system. The pressure should be around 58 psi for a 2006 PT Cruiser.

If you are not comfortable performing these diagnostic steps, take the vehicle to a qualified mechanic. Fuel system work involves pressurized lines, and safety should always come first.

The Right Time to Replace Your Fuel Pump

A fuel pump is not a lifetime part. Most OEM pumps last between 100,000 and 150,000 miles, but that number can drop significantly if the car is frequently driven on a low fuel level. If your PT Cruiser has high mileage and you are experiencing intermittent starting issues, stalling, or a loss of power under load, the pump is likely on its way out.

When the pump fails, do not be tempted to install a cheap aftermarket unit. A low-quality pump often has a shorter lifespan and may not deliver the correct pressure, which can damage the engine over time. Instead, choose a reputable brand that offers OEM-compatible specifications.
