How to Effortlessly Replace Your Vehicle’s Fuel Pump Driver Module
The main role of a fuel pump driver module is to control the voltage needed to operate a vehicle's fuel pump. By doing this, it helps maintain the right amount of fuel pressure going to the engine. A failing fuel pump driver module is not an unusual thing to come about, since this component is one the most vulnerable parts of your vehicle's fuel system. Poor engine performance is the most prevalent indication of a faulty fuel pump driver module. Replacement is the best solution if you've been experiencing this symptom. Here's how you can do it as a DIY task:
Difficulty level: Moderate
What you'll need:
- Socket set
- Replacement fuel pump driver module
- Owner's manual
Step 1: Park your car on a flat and level surface to ensure that it will not shift while you're doing the rest of the procedure. Since you're working with the fuel system of your vehicle, you need to make sure that there are no flammable devices and chemicals near you. It's highly recommended that you do this procedure on an isolated place to ensure maximum safety.
Step 2: Carefully release the fuel system pressure by removing the fuel pump relay first before letting the engine go idle until it stalls. Releasing the pressure prevents the fuel from dangerously spraying once you disconnect a fuel system component. It's absolutely important that you do this procedure when it comes to servicing any part of your vehicle's fuel system.
Step 3: Raise your car's hood and locate the battery. Carefully disconnect the negative cable from its ground terminal.
Step 4: Open the trunk of your car and locate the fuel pump driver module. This is usually found at the driver's side of the rear passenger seat. If you can't find its exact location, consult your vehicle's manual for additional instructions.
Step 5: Once you've successfully found the fuel pump driver module, pull up the carpeting over the area where it's located. After pulling back the carpet, you'll be able to gain unrestricted access to the fuel pump driver module. This generally looks like a small black rectangular box that's bolted onto your vehicle's body.
Step 6: Remove the damaged fuel pump driver module from your car by simply detaching the bolts that's securing it in place. Take a wrench and start unfastening them one by one. Make sure that you place each bolt on an organized area to keep them from getting lost.
Step 7: After successfully unbolting the faulty fuel pump driver module, detach the wires connected to its bottom portion. Do this with care to avoid damaging any of the wiring harness.
Step 8: Put the replacement fuel pump driver module in place.
Step 9: Plug the wires into the new fuel pump driver module, and then secure it with bolts. Make sure that it's properly aligned in its mounting place to keep it from getting damaged or detached.
Step 10: Reconnect the negative cable to the battery and reattach the fuel pump relay as well.
The whole process of replacing a damaged fuel pump driver module on your vehicle takes about one and a half hour to finish.
