Replacing Fuel Pump In Pt Cruiser: Step-By-Step Guide

The fuel pump in a Chrysler PT Cruiser is located in the fuel tank. To replace it, you will need to relieve the fuel system's pressure, remove the fuel tank, and replace the pump module. This is a complex process that requires specialised tools and knowledge, so it is recommended that you consult a qualified mechanic or repair shop. However, if you are confident in your abilities, there are online resources that can guide you through the process.

The fuel pump is located in the trunk area under an access flap

To change the fuel pump in a PT Cruiser, you'll first need to locate it. The fuel pump is located in the trunk area, under an access flap.

Once you've located the access flap, you'll need to remove it to access the fuel pump. Before doing so, it's important to relieve the fuel system's pressure. To do this, remove the fuel cap and open the hood. Then, remove the cover on the air filter housing and take out the fuel pump relay from the fuse box located behind and below the filter housing. Start the engine and let it idle until it stalls. Turn off the ignition and disconnect the negative battery cable.

Now that the pressure has been relieved, you can proceed to remove the access flap and access the fuel pump. Raise the rear end of the car and support it on jack stands. Unscrew and remove the drain cap on the fuel tank to allow the fuel to drain into a gas can or drain pan. Be sure to use a container that can hold up to 16 gallons of fuel.

With the fuel drained, you can now disconnect the fuel vapor hose and loosen the hose clamp for the fuel filler neck hose using a screwdriver. This will allow you to disconnect the hose from the fuel fill pipe. Place a transmission jack under the tank to support it, or use a floor jack with a piece of plywood on top to prevent damage to the tank.

At this point, you should be able to access the fuel pump and begin the process of replacing it. Be sure to have a suitable replacement fuel pump on hand, as well as any necessary tools and safety equipment. Always refer to a reputable repair manual or seek the assistance of a qualified mechanic if you're unsure about any part of the process.

The fuel filter is built into the fuel pump module

The fuel filter in the PT Cruiser is built into the fuel pump module, which is mounted inside the fuel tank. This means that to replace the filter, you'll need to replace the entire pump module. It's likely that if the filter is in poor condition, the pump will need replacing too.

To remove the pump module, you must first relieve the fuel system's pressure. Open the hood, remove the cover on the air filter housing, and take out the fuel pump relay from the fuse box. Then, start the engine and let it idle until it stalls. Turn off the ignition and disconnect the negative battery cable.

Next, raise the rear end of the car and support it on jack stands. Remove the drain cap on the tank and let the fuel drain into a suitable container. Disconnect the fuel vapor hose and loosen the hose clamp for the fuel filler neck hose, disconnecting it from the fuel fill pipe.

Use a transmission jack to support the tank from below; if you don't have one, a floor jack with a piece of plywood on top will also work. Disconnect the EVAP line and fuel supply hose at the quick-connect fitting, and then disconnect the electrical connector for the fuel pump module.

Now, you can unbolt the tank support straps and lower the tank. To remove the fuel pump module, squeeze the locking tabs for the fuel supply line and electrical connector to disconnect them. Draw an alignment marker on the fuel tank to ensure the correct positioning of the new module. Unscrew the module's locknut with water pump pliers and remove it from the tank, being careful not to bend the fuel sending unit float arm.

Install the new fuel pump and filter, screwing the locknut into place and using the mark you made to align the module. Connect the fuel supply hose and electrical connector. Raise the tank back into position, bolt the straps on, and connect the filler, vapor, and EVAP lines, along with the electrical connector.

Finally, lower the car off the jack stands, refill the fuel tank, and reconnect the battery cable and fuel pump fuse.

You must relieve the fuel system's pressure before removing the fuel pump

It is important to relieve the fuel system's pressure before removing the fuel pump from your PT Cruiser. This is because the fuel system operates under high pressure, even when the engine is shut off. If you don't relieve the pressure, you will be squirted by high-pressure fuel when you remove the fuel pump.

There are several methods to relieve the pressure, depending on your vehicle's make and model. Here is one common method:

First, disconnect the negative battery cable using a wrench. This will prevent sparks, which could ignite fuel and fuel vapors.

Next, locate the fuel pump fuse, usually under the dashboard or in the engine compartment. It is typically on the driver's side and marked for easy identification. You can also refer to your owner's manual to locate the fuse. Remove the fuse with your hand or a pair of pliers.

Now, start the engine and let it idle until it stalls. Then, turn off the ignition switch.

Finally, disconnect the negative battery cable again.

By following these steps, you can safely relieve the fuel system's pressure and proceed with removing the fuel pump from your PT Cruiser.

It is important to note that working on a fuel system can be dangerous, and you should always refer to your vehicle's service manual or seek professional assistance if you are unsure about any part of the process.

Disconnect the negative battery cable before attempting to remove the fuel pump

Disconnecting the negative battery cable is one of the first steps to take when attempting to remove the fuel pump in a PT Cruiser. This is because the fuel system's pressure must be relieved before removing the fuel pump.

To disconnect the negative battery cable, first open the hood of the car. Then, locate the negative battery cable. It should be clearly marked with a "-" symbol. Once you have located the cable, use a wrench or socket to loosen the nut that secures the cable to the battery terminal. Be sure to disconnect the cable from the negative terminal, not the positive terminal.

After the cable is disconnected, you will need to move on to the next steps of relieving the fuel system's pressure. This includes removing the fuel cap, removing the cover on the air filter housing, and removing the fuel pump relay from the fuse box. Once these steps are completed, you can proceed with removing the fuel pump from the PT Cruiser.

It is important to note that working on a fuel system can be dangerous, and it is always best to consult a professional or a repair manual before attempting any repairs.

You will need to remove the tank to remove the pump module

To remove the fuel pump module, you will need to remove the tank from your PT Cruiser. Here is a step-by-step guide on how to do this:

Step 1: Relieve the fuel system's pressure

Remove the fuel cap and open the hood of your car. Remove the cover on the air filter housing and take out the fuel pump relay from the fuse box located behind and below the filter housing. Start the engine and let it idle until it stalls. Turn off the ignition and disconnect the negative battery cable.

Step 5: Disconnect the EVAP line, fuel supply hose, and electrical connector

Disconnect the EVAP line and fuel supply hose at the quick-connect fitting. Also, disconnect the electrical connector for the fuel pump module.

Step 6: Lower and remove the tank

Unbolt the tank support straps with a wrench and lower the jack to remove the tank.

Step 7: Remove the fuel pump module

To remove the fuel pump module from the tank, first, disconnect the fuel supply line and electrical connector. Draw an alignment marker on the fuel tank to correctly line up the fuel pump module upon re-installation. Unscrew the module's locknut with water pump pliers and remove the module, being careful not to bend the fuel sending unit float arm.
