How does the fuel pump in a Honda Accord work?
by Jin Machina. The fuel pump in your Honda Accord pressurizes gasoline and distributes it into the fuel injectors and the engine. Look out for a few symptoms of a failing fuel pump when considering its replacement.
What should fuel pressure be on Honda Accord?
Start the engine, and let it idle for 2 minutes. 3. Turn off the engine. Check the fuel pressure gauge. Pressure should be 380 to 430 kpa (55 to 63 psi). 4. Monitor the fuel pressure reading. If the fuel pressure bleeds down quickly after the engine is turned off, go to the Repair Procedure.
What are the symptoms of a Honda Accord idle?
Other symptoms include an engine that lopes in idle, or idles unpredictably. Your Accord’s fuel pump may leak fuel around the fuel tank and become noisy while the car is running.
How do you install a fuel tank on a Honda Accord?
Align the marks on the fuel tank unit and the fuel tank. (See page 11-327, step 11 of the 2003-’06 Accord V6 Service Manual Supplement.) Install the fuel tank unit into the tank without dislodging the gasket. Using hand pressure only, slide the fuel tank unit into the tank until it is properly seated.
What happens when the fuel pump goes out on a Honda Accord?
There are physical signs that you can feel when your Accord’s fuel pump is going out. Before taking anything apart, check to see if your engine’s computer has any trouble codes saved in it. The engine may throw a P0087 trouble code. This trouble code detects that the fuel rail/system pressure is too low.
What does a bad fuel pump sound like?
A priming fuel pump sounds like a high-pitched whine for a few seconds and can be heard with a sharp engine right after the ignition key is turned, but before the starter is engaged. The symptoms of a bad fuel pump match a lot of other common problems that can occur in the Honda Accord.
Where is the fuel pump in a car?
The fuel pump is located in the fuel tank, near the rear of the vehicle and can usually be heard when the engine starts. A healthy fuel pump plus a healthy fuel pump relay will often produce a variation of a low volume hum or whine which can be heard from inside the vehicle, or from the outside, near the fuel tank.
How does a fuel pump relay work in a car?
It is usually controlled by the ignition or the power control module. When you turn on the ignition, the fuel pump relay is activated and will supply electricity to turn on the fuel pump.
Why does my fuel pump not prime when I turn it on?
Pulled fuel pump relay and put in a jumper wire to run the fuel pump and it started. Put the fuel pump relay back in and it starts and drives, but the fuel pump still doesn’t prime when turning the key on. I’m afraid that after sitting overnight, it will once again refuse to start.
How can you tell if your fuel pump is faulty?
Since the fuel pump essentially delivers the fuel to the engine, some of the first signs of a failing fuel pump show through engine operations. For example, if the engine rotates but doesn’t start or your Accord boosts in acceleration when you press the gas pedal consistently, the fuel pump may be faulty.
What to do if your fuel pump won’t start?
Ugh…..I hate chasing down electrical problems. If jumping the fuel pump relay makes the pump run, and if the relay tests good. Then you need to determine why the ECM is not telling the relay to close. Start by testing continuity back to the ECM.
Why does my fuel pump not prime with the key on?
Fuel pump doesn’t prime with key on. I’ve been trying to figure this out for a couple days now. My 01 Tiburon wouldn’t start the other day. It would crank, but wouldn’t fire. When I turn the key to the “on” position, the fuel pump doesn’t kick on.
