DIY or professional installation:

• DIY is possible for mechanically inclined individuals. However, professional installation is recommended if you are not comfortable working on your car's fuel system. Incorrect installation can be dangerous.

Compare: Used OEM, New Aftermarket

• Used OEM: These are genuine factory parts that were originally installed in the vehicle. They are typically tested and inspected to ensure they are working properly. They offer excellent value.
• New Aftermarket: These are brand new parts made by third-party manufacturers. They are designed to meet or exceed the original equipment specifications.

Used OEM: Best value

• Genuine factory parts.
• Tested and inspected.
• Significantly lower prices than new.

New Aftermarket: Brand new

• Third-party parts.
• Built to OE specs.
• Can be a good alternative to OEM.

Parts commonly replaced or checked:

• Fuel Pump: The fuel pump and fuel pump control module work together. If one fails, the other might be stressed.
• Fuel Filter: A clogged fuel filter can put extra strain on the fuel pump and control module.
• Fuel Pump Relay: This relay provides power to the fuel pump. A faulty relay can cause fuel pump problems.

Why replacing related parts prevents repeat failures:

• Replacing related parts can prevent future problems by addressing the root cause of the failure. For example, if a clogged fuel filter caused the fuel pump control module to fail, replacing the filter will prevent the new module from failing prematurely.

How long this part normally lasts:

• A fuel pump control module can last for 80,000 to 150,000 miles or more.

Factors that affect longevity:

• Driving Conditions: Harsh driving conditions, such as frequent stop-and-go traffic, can shorten the lifespan of the module.
• Fuel Quality: Using low-quality fuel can damage the fuel pump and put extra strain on the module.
• Maintenance: Regular maintenance, such as changing the fuel filter, can help extend the lifespan of the module.
• Heat: Excessive heat can damage the module.

Budget vs mid-range vs premium options:

• Used OEM: $50 - $150
• New Aftermarket: $100 - $300

Labor cost considerations:

• Labor costs can range from $100 to $300, depending on the shop and the complexity of the job.

Total job cost estimates:

• Used OEM + Labor: $150 - $450
• New Aftermarket + Labor: $200 - $600

Known issues:

• Some Cadillac, Chevrolet, and GMC vehicles have had issues with fuel pump control module failures due to overheating. Relocating the module to a cooler location can help prevent future failures.
• Some owners have reported issues with aftermarket modules not performing as well as the original OEM module.

TSBs or common complaints:

• Check for any Technical Service Bulletins (TSBs) related to the fuel pump control module for your specific vehicle.

How to confirm proper operation:

• Start the engine and let it idle for a few minutes.
• Check for any fuel leaks.
• Drive the car and see if it accelerates smoothly.
• Use a scan tool to check for any new diagnostic trouble codes (DTCs).

What to look/listen for:

• Smooth Acceleration: The engine should accelerate smoothly without hesitation.
• Normal Idle: The engine should idle smoothly without stalling.
• No Unusual Noises: You shouldn't hear any unusual noises from the fuel pump or fuel tank area.
• No Check Engine Light: The check engine light should be off.

Q: How do I know if my fuel pump control module is bad?
A: Common symptoms include engine stalling, hard starting, reduced fuel economy, and a check engine light.

Q: Can I replace the fuel pump control module myself?
A: Yes, if you have mechanical experience. But professional installation is recommended for safety.

Q: Will a new fuel pump control module need to be programmed?
A: In some cases, yes. Check your vehicle's service manual or consult a mechanic.

Q: What's the difference between a used OEM and a new aftermarket fuel pump control module?
A: Used OEM parts are original factory parts, while new aftermarket parts are made by third-party manufacturers.

Q: How long does a fuel pump control module typically last?
A: It can last for 80,000 to 150,000 miles or more, depending on driving conditions and maintenance.
