Fuel pump location

Hi blitz210,

It requires a signal from the ignition coil, is the tachometer working?

Btw if it has an ECU under the passenger seat, then it might be causing the problem.

You can use a jumper to make it work direct, but in case of an emergency, the fuel pump would still be working if the engine is cut off with the ignition switch on.

When its not starting you need to check for spark and for fuel pressure
if no spark most likely its the module inside the distributor
and you need to replace it

Hi tuesday777,

If it is fuel that is not being supplied, try changing the main relay, many similar cases have been caused by the relay.

Hi stevec217,

Fuel filter location.

Under hood, driver side, front side of strut tower, mounted on fenderwell in fuel line

I would check the fuel pump in fuel tank.

Hi jcfarber,

The fuel pump is located at lower front of the rear Left wheel arch and it is not a rotary type so there will be a ticking noise when it is operating. This is normal. Replacement does not require removal of fuel tank.

Rough idling could be due to many factors.
1. Different compression of cylinders.
2. Bad spark plugs, wires etc.
3. Leaking vacumn lines
4. Faulty/out of adjustment carburettor

The fuel pump on my honda went out I understand-Do you hear it when key at On position if so check the fuel pressure-if not power issue-get back

Hi timsmo,

The fuel pump is in tank but groaning noise during hard turns are not likely to be due to it.

It is a problem most likely to be related to the suspension system.

Without the physical vehicle, it would be almost impossible to diagnose the problem and the only way is to try to locate the source.

Hello -

To better assist you is your model the DX, EX or LX and please tell me your engine size in liter?

Hello -

It is much better if you know if the engine is a 2.3L, 2.4L or 3.0L as there may be something different with them and I don't want to mislead you. I do want to provide the best info I can. . .so if you can find out the size in liter that would be better.

For now to make sure we are looking at the right thing, take some starting fluid and spray into the throttle body and see if it tries to start.

Should take about 2 hours to change. . ..book says about 1.3

Do you have any fuel pressure at all?

Make sure you checked with an ohm meter, fuses 1, 11, 13

The fuel pump is located in the tank but you get to it through the trunk, there is a access panel in there. . .. . .. . .(that is great and very lucky. . ..many cars you have to drop the tank)

As for the fuel pump replacement here are the direction for an LX. . .but I again, still would like to know the engine size in liter to make sure all my info to you applies to your model.

FUEL PUMP REPLACEMENT

1. Remove the trunk floor.

2. Remove the access panel from the floor.

3. Turn the ignition switch OFF, then disconnect the fuel pump 5P connector.

4. Remove the fuel cap.

5. Relieve the fuel pressure (see Fuel Pressure Relieving ).

6. Disconnect the quick-connect fittings from the fuel pump.

7. Remove the bolts (A), and the fuel tank unit (B).

8. Remove the bracket (A), the fuel filter (B), the fuel gauge sending unit (C), the hose (D), and the wire harness (E).

9. When connecting the fuel pump, make sure the connection is secure and the suction filter (H) is firmly connected to the fuel pump (I).

10. Install the parts in the reverse order of removal with a new base gasket, then check these items:
"Â When connecting the wire harness, make sure the connection is secure and the terminal (F) is firmly locked into the place.
"Â Check that the tab of the clamp (G) does not interfere with the wire harness.
"Â Do not push the lower part of the suction filter.
"Â When installing the fuel gauge sending unit, make sure the connection is secure and the connector is firmly locked into place. Be careful not to bend or twist it excessively.

FUEL PRESSURE RELIEVING

Before disconnecting fuel lines or hoses, release pressure from the system by loosening the fuel pulsation damper on top of the fuel rail.

1. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio's preset buttons.

2. Disconnect the negative cable from the battery.

3. Remove the fuel fill cap.

4. Use a wrench on the fuel pulsation damper (A) at the fuel rail.

5. Place a rag or shop towel (B) over the fuel pulsation damper.

NOTE: Replace all washers whenever the fuel pulsation damper is loosened or removed.

6. Slowly loosen the fuel pulsation damper one complete turn.

Here is a check you can do for the fuel pump.

FUEL PUMP TEST

If you suspect a problem with the fuel pump, check that the fuel pump actually runs; when it is ON, you will hear some noise if you listen to the fuel fill port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned on. If the fuel pump does not make noise, check as follows:

1. Remove the trunk floor

2. Remove the access panel from the floor.

3. Turn the ignition switch OFF, then disconnect the fuel pump 5P connector.

4. Connect the PGM-FI main relay 7P connector terminals No. 4 and No. 5 with a jumper wire.

5. Turn the ignition switch ON (II).

6. Check that battery voltage is available between the fuel pump 5P connector terminal No. 5 and body ground when the ignition switch is turned ON (II).
"Â If battery voltage is available, check the fuel pump ground. If the ground is OK, replace the fuel pump (see Fuel Pump Replacement ).
"Â If there is no voltage, check the wire harness (see PGM-FI Main Relay Circuit Troubleshooting ).

Hello -

Please make sure you read the directions carefully to prevent any problems. The relay is on the car under the dash... As it says you put a jumper wire from the 4 to the 5 plug on the wire side of the female terminals....... Then check your fuel pump plug.

Hope this helps

Hi markthree, Welcome to 2carpros and TY for the donation.

Do you hear the fuel pump come On when you turn key to run if so check the fuel pressure.

Use a wrench to remove the fuel pulsation damper from its fitting.

8. Attach the fuel pressure gauge.
9. Disconnect the vacuum hose (A) from the fuel pressure regulator (B) and pinch it closed with a clamp (C).
10. Start the engine and let it idle.

o If the engine starts, go to step 12.
o If the engine does not starts, go to step 11.

11. Check to see if the fuel pump is running: remove the fuel fill cap and hold your ear to the fuel fill port while an assistant turns the ignition switch ON (II) you should hear the pump run for about two seconds when the ignition turned ON (II).

o If the fuel pump runs, go to step 12.
o If the fuel pump does not run, test it.

12. Read the pressure gauge (with the fuel pressure regulator vacuum hose disconnected and clamped). The pressure should be 320 - 370 kPa (3.3-3.8 kg/sq.cm, 47-54 psi) .

o If the pressure is OK and engine is running, go to step 13. If not running, repair the cause, then continue this test.
o If the pressure is out of spec, go to step 14.

13. With the engine running, unpinch and reconnect the vacuum hose and read the gauge again. The pressure should be 260 - 310 kPa (2.7-3.2 kg/sq.cm, 38-46 psi) .

o If the fuel pressure is OK, the test is complete.
o If the pressure is out of spec, go to step 14.

14. Disconnect the vacuum hose from the pressure regulator again while you watch the pressure gauge. The pressure should rise when you disconnect the hose.

o If the pressure did not rise, replace the fuel pressure regulator.
o If the pressure is rose, but all your readings were lower than specified, check for a clogged fuel filter and for leaks in the fuel lines.
o If the pressure is rose, but all your readings were higher than specified, check for a pinched or clogged fuel return hose or line.

15. Reconnect the vacuum hose, remove the pressure gauge, and reinstall the fuel pulsation damper and a new washer. Tighten the fuel pulsation damper to 22 Nm (2.2 kg/sq.cm, 16 lb.ft) . NOTE: Disassemble and clean the fuel pressure gauge attachment thoroughly after use.
