Replacing The Fuel Pump Relay In Your 1998 Mustang

Replacing the fuel pump relay in a 1998 Mustang can be a tricky task. The first step is locating the fuel pump relay, which is part of the Constant Control Relay Module (CCRM) and can be found in the engine compartment or behind the passenger-side wheel well plastic cover, near the air cleaner. Once located, one can access and remove the connector using a 5mm nut wrench. This will allow for the removal of one of the two bolts holding the module bracket to the fender. With the CCRM accessible, the fuel pump relay can be replaced. It is important to note that there may be variations in the location and replacement procedure depending on the specific model and year of the Mustang.

The fuel pump relay is in the CCRV Box in the passenger side fender well

To replace the fuel pump relay in a 1998 Mustang, you'll first need to locate the Constant Control Relay Module (CCRM), which is housed in the CCRV Box in the passenger side fender well. This is located behind the passenger side wheel well's plastic cover.

To access the CCRM, you'll need to remove the tire and wheel well cover. With the cover removed, you'll see the CCRM—it's a square box with a large connector, located at the 1 o'clock position when looking directly at the tire.

The CCRM contains several relays, including those for the fuel pump, cooling fan, and air conditioning clutch. To remove the fuel pump relay, you'll need to disconnect the connector from the module. A 5mm nut wrench is the right size to remove the connector.

Once the connector is removed, you can access the bolts that hold the module bracket to the fender and remove the old relay. Install the new relay, secure the bracket, and reconnect the connector.

It is important to note that there are two fuel pump relays in the 1998 Mustang GT. The main power relay is in the CCRM, while the relay near the PCM is the fuel pump speed relay.

To access the relay, you need to remove the wheel and wheel well cover

To access the fuel pump relay on a 1998 Mustang, you will need to remove the wheel and wheel well cover on the passenger side. This is because the relay is located in the Constant Control Relay Module (CCRM) box, which is situated behind the plastic liner of the wheel well.

First, remove the wheel and wheel well cover. Then, looking at the wheel dead-on, the CCRM box should be located at the 1 o'clock position. To confirm its location without removing any plastic cover, you can pop the hood and look for a wire harness routing from the engine compartment into the passenger side front fender, near the air cleaner. Shine a light in there, and you will see a connector attached to the module.

Once you have located the CCRM box, you can then proceed to remove the relay and replace it with a new one.

The relay is housed in a Constant Control Relay Module (CCRM)

The 1998 Mustang's fuel pump relay is housed in a Constant Control Relay Module (CCRM). This module is located behind the passenger side wheel well's plastic cover. To access it, you'll need to remove the wheel and the inner fender liner.

The CCRM is a metal base with a plastic cover that serves as a home for a circuit board with several integrated relays. Typically, it has four or five relays:

• PCM relay
• High-speed cooling fan relay
• Low-speed cooling fan relay
• Fuel pump relay
• A/C clutch/compressor relay

The CCRM provides power to the powertrain control module (PCM) for various components on the Mustang, including the Fuel Pump Driver Module (FPDM). If you're experiencing any issues where the PCM, cooling fan, air conditioner compressor clutch, or fuel pump is not getting power, the CCRM may be faulty.

To replace the CCRM, first disconnect both battery cables from the battery. Then, remove the wheel and inner fender liner to access the CCRM wiring. Next, use a 5mm socket to remove the wiring harness connection from the CCRM. Once the wiring harness is loosened, pull it away from the module. Finally, remove the two 5.5mm bolts retaining the CCRM to the mounting bracket, and you can completely remove the CCRM from the bracket.

It's important to note that V6 and V8 CCRMs are different, and the 2001-2004 CCRM is different from the older 1994-2000 models. So, when installing a replacement, double-checking the part number is essential.

The CCRM contains the relay for the fuel pump, cooling fan, and air conditioning clutch

The Constant Control Relay Module (CCRM) is a component in the 1994-2004 SN95 Mustang that provides vehicle power to the powertrain control module (PCM) for various components. These include the fuel pump, cooling fan, and air conditioning clutch. The CCRM is typically located in the passenger side fender well, behind the plastic liner, and can be accessed by removing the wheel and inner fender liner.

The CCRM plays a crucial role in the electrical system of the Mustang, and issues with it can lead to a range of problems. For example, if the PCM, cooling fan, air conditioner compressor clutch, or fuel pump is not getting power, the CCRM may be faulty and need replacement.

To replace the CCRM in a 1996-2004 Mustang, first disconnect both battery cables. Then, remove the wheel and inner splash shield to access the CCRM. Next, use a 5mm socket to remove the wiring harness connection from the CCRM, and pull the harness away from the module. Finally, remove the two 5.5mm bolts retaining the CCRM to the mounting bracket, and completely remove the CCRM from the bracket.

It is important to note that the V6 and V8 CCRMs are different, and the 2001-2004 CCRM is different from the older 1994-2000 version. Therefore, when installing a replacement CCRM, it is crucial to double-check the part number to ensure compatibility.

The CCRM is located behind the passenger side wheel well plastic cover

The Constant Control Relay Module (CCRM) is located behind the plastic cover of the passenger side wheel well of a 1998 Mustang. To confirm its location without removing the plastic wheel well cover, you can pop the hood and look for a wire harness that is routed from the engine compartment into the passenger side front fender, near the air cleaner. Shining a light in this area will allow you to see a connector attached to the module.

A 5mm nut wrench can be used to remove the connector from the module, allowing access to one of the two bolts that hold the module bracket to the fender. This is the first step in replacing the fuel pump relay.

The CCRM is a small, square box with a large connector, located at the 1 o'clock position when looking directly at the wheel. It contains the relay for the fuel pump, cooling fan, and air conditioning clutch.
