1987 Honda Accord Fuel Pump: Complete Guide to Replacement, Diagnosis, and Upgrade
If your 1987 Honda Accord is cranking but not starting, or you hear a whining noise from the rear of the car, the fuel pump is almost certainly the culprit. The 1987 Accord uses an electric fuel pump mounted inside the fuel tank, accessible through a panel in the trunk—no need to drop the gas tank. Replacing it is a straightforward DIY job that costs around $70 for parts and takes about one to two hours. The most common failure point is the pump itself, not the filter or wiring, so replacing the pump with a quality aftermarket unit is the smartest fix.
How the Fuel Pump Works on Your 1987 Honda Accord
The 1987 Honda Accord uses an electric fuel pump that is submerged inside the fuel tank . When you turn the key to the "ON" position, the pump primes for about two seconds, building pressure so the engine can start. If you do not hear that brief hum from the rear of the car, the pump is not working.
The pump is located on the left side of the trunk floor, under a metal access panel . This design is a huge advantage—you do not need to lower or remove the fuel tank to access the pump. The original Honda part number for the fuel pump unit assembly on the 1987 Accord (DX and LX models) is 17708-SE0-S06, but this part has been discontinued .
Symptoms of a Failing Fuel Pump
Before you start replacing parts, confirm the pump is actually the problem. The three most common signs of a bad fuel pump on a 1987 Accord are:
- Engine cranks but will not start. This is the most obvious symptom. The engine turns over but never fires because no fuel is reaching the injectors or carburetor (depending on your trim).
- No priming sound. When you turn the key to the "ON" position, you should hear a brief humming or buzzing from the trunk area. If you hear nothing, the pump is either dead or not getting power.
- Whining or loud noise from the tank. A failing pump often makes a high-pitched whining sound before it dies completely. This is a warning sign that the pump is struggling.
Other symptoms include hesitation during acceleration, surging at highway speeds, or a car that starts fine when cold but struggles when hot. These can also point to a clogged fuel filter, so always check the filter first. It is cheap and easy to replace.
How to Replace the Fuel Pump on a 1987 Honda Accord
Replacing the fuel pump is a job most DIYers can handle in their driveway. Here is the step-by-step process based on actual repair guides and owner experiences .
Step 1: Safety First
Disconnect the negative battery terminal. This is critical because you are working near fuel and electrical connections. Also, open the gas cap to relieve any pressure in the tank. No smoking, no open flames, and no running appliances near the work area.
Step 2: Access the Pump
Open the trunk. Remove the spare tire cover and any carpet or trim on the left side of the trunk floor. You will see a metal disc (about 6–8 inches in diameter) sealed to the floor. Pry it up with a screwdriver to reveal the fuel pump assembly .
Step 3: Disconnect the Old Pump
Use pliers to remove the fuel line clamp, then pull the fuel line off the pump fitting. Be prepared for a small amount of fuel to spill. Unplug the electrical connector. Use a socket to remove the six bolts holding the pump assembly in place. Lift the entire assembly out of the tank .
Step 4: Install the New Pump
Remove the old pump from the mounting bracket. Most aftermarket pumps come with new strainers, seals, and instructions. Install the new pump onto the bracket, making sure the fuel line and electrical connections are secure. Place the assembly back into the tank, tighten the six bolts, reconnect the fuel line and electrical connector, and replace the access panel.
Step 5: Test
Reconnect the battery. Turn the key to "ON" and listen for the pump to prime. The car should start normally. If it does not, double-check the electrical connections and fuel line.
Common Mistakes to Avoid
Forgetting the fuel filter. When you replace the pump, you should also replace the inline fuel filter. The original OEM filter will not fit the new pump, so you must buy a new filter separately . This is a common oversight that can cause the new pump to fail prematurely.
Using cheap, unbranded pumps. Low-quality aftermarket pumps often fail within months. They may not deliver the correct flow rate or pressure, and they can damage your engine by causing a lean fuel mixture .
Not checking the wiring. Before replacing the pump, test the electrical connector with a multimeter. If the pump is not getting 12 volts, the problem may be a bad relay, fuse, or wiring issue, not the pump itself .
