1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Mopar 68193711AC Fuel Pump Control Module. Please read this manual thoroughly before attempting any installation or service to ensure safe and correct usage.
2. Safety Information
WARNING: Improper installation or handling of fuel system components can lead to serious injury, fire, or property damage. Professional installation is highly recommended.
- Always disconnect the vehicle's battery before working on any electrical or fuel system components.
- Ensure the work area is well-ventilated and free from open flames or sparks.
- Wear appropriate personal protective equipment, including safety glasses and gloves.
- Fuel is highly flammable. Handle with extreme care and be prepared for potential fuel spills.
- Refer to your vehicle's service manual for specific procedures and torque specifications.
3. Product Overview
The Mopar 68193711AC Fuel Pump Control Module is an original equipment (OE) component designed to regulate the voltage supplied to the fuel pump. This regulation allows for precise control of fuel pressure, optimizing engine performance and fuel efficiency. The module is typically located near the fuel tank or within the vehicle's chassis.

4. Setup and Installation
The installation of a Fuel Pump Control Module requires mechanical aptitude and specific tools. If you are not confident in your ability to perform this installation, it is recommended to seek assistance from a certified automotive technician.
4.1 Pre-Installation Checks
- Verify that the Mopar 68193711AC module is the correct part for your vehicle's make, model, and year.
- Gather necessary tools: wrenches, sockets, screwdrivers, battery terminal wrench, and a diagnostic scan tool (if available).
- Ensure the vehicle is parked on a level surface with the parking brake engaged.
4.2 Installation Steps
- Disconnect Battery: Locate the vehicle's battery and disconnect the negative (-) terminal first, followed by the positive (+) terminal. This prevents electrical shorts during installation.
- Locate Existing Module: Refer to your vehicle's service manual to find the exact location of the fuel pump control module. It is often found near the fuel tank, under the vehicle, or in the trunk area.
- Disconnect Electrical Connector: Carefully disconnect the electrical harness from the existing module. Be gentle to avoid damaging the connector or wiring.
- Remove Mounting Hardware: Unscrew any bolts or fasteners securing the old module to the vehicle chassis.
- Remove Old Module: Carefully detach and remove the old fuel pump control module.
- Install New Module: Position the new Mopar 68193711AC module in the correct orientation. Secure it with the original mounting hardware. Ensure it is firmly attached.
- Reconnect Electrical Connector: Plug the electrical harness firmly into the new module until it clicks into place. Double-check for a secure connection.
- Reconnect Battery: Reconnect the positive (+) battery terminal first, then the negative (-) terminal.
- Test System: Start the vehicle and check for proper operation. Listen for the fuel pump priming sound. If a diagnostic scan tool is available, check for any stored or pending diagnostic trouble codes (DTCs).
5. Operating Principles
Once correctly installed, the Mopar 68193711AC Fuel Pump Control Module operates automatically as part of the vehicle's engine management system. It receives signals from the Powertrain Control Module (PCM) to adjust the voltage supplied to the fuel pump, thereby controlling fuel pressure and volume delivered to the engine. This dynamic control ensures optimal fuel delivery under various driving conditions, contributing to efficient combustion and reduced emissions. No direct user interaction is required for its operation after installation.
6. Maintenance
The Mopar 68193711AC Fuel Pump Control Module is a sealed electronic component and does not require routine maintenance or user-serviceable parts. However, periodic visual inspection during other vehicle maintenance can help identify potential issues:
- Check the module's housing for any signs of physical damage, cracks, or corrosion.
- Inspect the electrical connector and wiring for fraying, corrosion, or loose connections.
- Ensure mounting hardware remains secure.
If any damage or unusual conditions are observed, consult a qualified technician for further inspection and diagnosis.
7. Troubleshooting
If you experience issues that you suspect are related to the fuel pump control module, consider the following common symptoms and steps:
7.1 Common Symptoms of a Faulty Module
- Engine cranks but does not start.
- Engine stalls intermittently.
- Poor engine performance, such as hesitation or lack of power.
- Check Engine Light (CEL) illuminated on the dashboard.
- Diagnostic Trouble Codes (DTCs) related to fuel pressure or fuel pump control.
7.2 Diagnostic Steps
- Check for DTCs: Use an OBD-II scanner to retrieve any stored diagnostic trouble codes. Codes related to fuel pump control circuits (e.g., P0230, P0231, P0232) may indicate a module issue.
- Inspect Wiring: Visually inspect the wiring harness and connector leading to the module for any damage, corrosion, or loose pins.
- Fuel Pressure Test: A qualified technician can perform a fuel pressure test to determine if the fuel pump is receiving proper voltage and if the system is maintaining correct pressure.
If troubleshooting does not resolve the issue, or if you are unsure about performing these steps, it is strongly recommended to consult a certified automotive technician for professional diagnosis and repair.
