How to Repair Your Integra Fuel Pump

If your fuel tank has gas in it and your vehicle is having trouble getting gas into the carburetor, you may be having problems with your fuel pump. The fuel pump on an Acura Integra is electric. You can check your fuel pump, the fuses, and relays to make sure everything is working correctly. If it isn’t you can clean the fuel pump or replace it if necessary. The following steps will help you check your fuel pump and repair the item.


Check the Fuses

The first thing you should check is your fuse box. Find the fuse box and locate the fuse that goes to the fuel pump. Check that the fuse has not blown. Take the fuse out of the box and if it is blown the inside will have black or the wire in the middle will have a hole. If either of these are evident, then replace the fuse. Try to start and run the car again. If the car works, that was your problem. If the car still can’t get fuel, go to the next step.


Check the Relay

The relay for the fuel pump is located under the steering wheel. If you take off the dash just under the steering wheel you should see the relay. It is about the size of a chalkboard eraser but not quite as long. The color can be brown or gray. It can also be located slightly to the left and down from the fuse box. It will have a rust colored wiring harness with seven wires. To check the relay put your hand on the outside cover. When you turn the key on it fires to prime the fuel pump and then turns off when the check engine light goes out. Turn the key on, but don’t start the car, while holding your hand on the outside cover of the relay. Just turn the key to where your engine light comes on. You should feel a click in the relay when the key turns on and another one when the check engine light turns off. If you don’t feel either click, the relay needs to be repaired or replaced.


Replace the Fuel Filter

If you have checked the fuses and relay and still are not getting fuel to the vehicle, replace the fuel filter. You will find the fuel filter near the gas tank on one of the walls of the vehicle. The fuel comes through the fuel filter and goes to the engine. Make sure you install the new one with the arrow going the way the previous one had the arrow going. Relieve the pressure on the gas tank by opening the cap. Go to the area of the fuel filter and take off one line at a time. Take off the line going to the engine first and put that line on the new fuel filter. Then take the other line off and put it on the new filter. Put the filter back onto the side of the car. If you get sufficient fuel, that was your problem. If not, you need to replace the fuel pump.


Purchase the Correct Fuel Pump

Take the year of your car, the make, the model, and the size of your engine to the parts store. They will be able to take that information and give you the correct fuel pump for your car.


Remove the Fuel System Pressure

Take the kick panel out from under the dash and take out the relay that controls the fuel pump. Disconnect the negative battery cable, start your car, and let it run until it dies. Open the cap on your gas tank, but close the hatch so nothing gets into the gas tank.


Get Access to the Fuel Pump

Take out the back seat and set it aside. Remove the maintenance cover and set it aside. Unplug the fuel pump’s electrical connections.


Remove the Fuel Pump

Hold the connector for the fuel line in one hand and press down on the retaining tabs with your other hand. You should be able to pull the connector off while doing this. Cover the connector and pipe with plastic to prevent spills. Also, have a towel handy in case a spill does happen. Take off the nuts that keep the fuel pump in place. Remove the pump.


Install the New Pump

Install your new fuel pump using all the parts in the kit in the appropriate places. Be sure to use the new retainer. Use a torque wrench so you can tighten the bolts to 53 in. pounds.


Reconnect the Line and Electrical Connections

Reconnect the fuel line with the new retainer. Reconnect the electrical connection. Replace the relay, shut the gas cap, and replace the negative cable on your battery. Start the car and make sure you don’t have any leaks around the fuel pump. If it is leaking, shut everything off and take off the fuel line and reattach more securely. Try again.


Finish the Job

Once you know there are no fuel leaks, replace the maintenance cover and the back seat. Make sure your fuel relay is reinstalled, the kick panel is replaced, and the negative battery cable is reattached.

Integra fuel pumps are pretty easy to fix or replace. You may just be able to replace a fuse, replace the relay, or tighten your electrical connections to fix the problem. If you have a scan tool, you can use that to diagnose the problem with your fuel. If not, follow the steps above and you will be able to find and fix your fuel problem.
