There is no pump in the tank to pressurise the fuel. it is all pulled by vaccum. i would guess it is sucking air somewhere or you didn't clean the high pressure lines correctly and it is leaking fuel into the crankcase. also you shouldn't reseal the injector sleeves, they should be replaced and lock tight put on the tips when reinstalled

Code P1139 popped up in my 2000 Honda Accord. Changed the 02 Censor and spark plugs. Check engine light still flashes and is miss firing somewhere. Won't turn over at all.


the code refers to the heated oxygen sensor (HO2S) and not the O2 sensor which is a different sensor
It is a generic code and refers ti injector and fuel problems
The misfiring can be from injectors as well as plugs so check for fuel pressure and blocked fuel filter

1993 honda accord acts like running out of gas step on gas pedal and it runs ok for about .5 mile does it again


check for plugged exhaust system, it could be that a pipe has collapsed or the catalytic converter may be plugged up. check back pressure at the o2 sensor ( req' special tool) or drill small hole in exhaust system just ahead of the converter and use heavy duty fuel pressure gauge. Reading should be no more than 2 1/2 psi. If pressure is greater install new exhaust system starting w/ converter. If back pressure is ok, check fuel pressure and go by book specks. P.S make sure to weld up hole in exhaust after back pressure test. If converter and rest of exhaust checks out.

P1457 HONDA - Evaporative Emissions Control System Leakage EVAP Canister Systemxicon.jpghttp://engine-codes.com/p1457_honda.htmlForum CodePossible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap There is a Honda factory service bulletin with information on how to diagnose the P1456 on the following Honda models:
1998 Honda Accord
1999 Honda Accord
2000 Honda Accord
1998-2000 Honda Accord
symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vaporsP1457 HONDA Description The evaporative emission (EVAP) control system stores fuel vapor from the fuel tank in the EVAP canister temporarily to prevent it from escaping to the atmosphere and to enable it to be drawn into the engine by intake manifold vacuum and burned. In addition, the onboard refueling vapor recovery system (ORVR) stores fuel vapor generated when refueling in the EVAP canister.

The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two way valve to the fuel tank). There is 0.04 inch leak detection and 0.02 inch leak detection. If the 0.04 inch leak detection results are OK, the 0.02 inch leak detection runs. The P1457 code is detected when the EVAP system has a very small leak.

P0107 HONDA Description The Manifold Absolute Pressure sensor provides instantaneous manifold pressure information to the engine's Engine Control Module. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.


In some vehicles the absolute pressure sensor is built into ECM.

97 honda accord SE not getting power to fuel pump I drove my car over to my mothers house shut it off and went out to leave and my car would not start checked all the fuses and the relays then realized...


Three things you may want to check out next in your problem diagnosis:

1. You may actually be getting power to the fuel pump through the functioning fuel pump relay and the good fuse, but the fuel pump itself may have failed - you can check by disconnecting the fuel pump electrical connector, and checking for battery voltage when the ignition key is turned to "Start".

2. The ignition switch itself may have failed, since it has been recalled on this vehicle. The recalled defect may have caused a failure of the switch to deliver power to the fuel pump at startup. Here's a list of all the recalls for the 1997 Accord:

Recall - Ignition Switch Replacement 02-031 09/24/2002
Recall 02V120000: Ignition Switch Defect NHTSA02V120000 05/01/2002
Recall 99V069000: Lower Ball Joint Replacement NHTSA99V069000 04/20/1999
Recall 98V231000: Air Conditioner Wire Harness Chafing NHTSA98V231000 09/18/1998
Campaign - Front Balancer Shaft Oil Seal Replacement 00-073 03/13/2001
Recall - A/C Wiring Harness Routing 98-072 10/13/1998

3. Testing the PGM-FI main relay is fairly involved (and not detailed in the information below). You may want to re-post your query asking for the testing & diagnosis procedure for this component alone.

Below find the 1997 Honda Accord manual entry for diagnosis & testing of the fuel pump electrical circuit.

TESTING

Fuel Pump Circuit

If you suspect a problem with the fuel pump, listen for the pump to operate by removing the fuel fill cap and checking to see if the pump can be heard running during the first two seconds after the ignition key is turned to the ON position. You should hear the fuel pump motor run.

If the fuel pump can be heard running, the fuel pump's electrical circuit is likely to be OK and the fuel pump operating pressure should be checked as outlined later in this section.

Once the engine has started, the fuel pump operation is controlled by the Powertrain Control Module (PCM) via the PGM-FI Main Relay. The fuel pump receives its electrical power from the PGM-FI Main Relay, which is triggered for two seconds when the ignition switch is initially turned to the on position.

After the initial two-second startup signal is received, the PGM-FI Main Relay is controlled by the PCM. Because the fuel pump receives its power from the PGM-FI Main Relay, a problem with the ignition switch, PCM, or electrical wiring may not allow battery voltage to reach the pump.

To check the fuel pump wiring proceed as follows:

1. Make sure the ignition switch is in the OFF position.
2. Locate and detach the fuel pump electrical connector at the fuel tank.
3. You may have to remove the floor access panel. For specific details, see the fuel pump removal procedure in this section.
4. Fuel pump access is limited on some 1996-97 models of the Accord and may require you to work under the vehicle. Perform the following steps if that is the situation:

a. Raise the vehicle and safely support it on suitable jackstands.
b. Remove the protective cover from the fuel tank fuel hoses.

5. Detach the fuel pump electrical connector.
6. Connect a suitable Voltmeter between the fuel pump positive terminal of the electrical connector and a known good chassis ground.
7. Hold the electrical connector of the PGM-FI Main Relay so the wire side of the female terminals is visible and install a jumper wire between terminal Nos. 4 and 5.
8. When the ignition switch is turned ON , battery voltage should be present at the fuel pump electrical connector.
9. If the battery voltage is present, check the fuel pump's ground.
10. If the ground is "OK", check the fuel pump.
11. If battery voltage is not present, trace the wiring harness and check the cause for an open or shorted circuit.
12. If all wiring checks out, test the fuel pressure, as outlined later in this section.

Fuel Pump Pressure

The fuel pressure should be checked at the fuel rail or at the fuel feed line for the fuel rail. The fuel pressure is checked with the engine started, thus the fuel pressure gauge must not interrupt the flow of fuel to the fuel rail and the fuel injectors.

To attach a fuel pressure gauge to the pressurized fuel loop requires the use of an adapter that is capable of safely withstanding the fuel system fuel pressure.

WARNING
Checking the fuel system fuel pressure requires the use of an in-line fuel pressure gauge with the engine running. Do not perform this check if suitable test equipment and fuel fittings are not available. The fuel system operates under pressure, if any fuel leakage is noticed while performing this check STOP immediately and do not continue until the source of the leak is resolved. Do not perform this test near sources of heat, spark, or flames. This test must be performed in a well-ventilated area.


CAUTION
The fuel injection system remains under pressure, even after the engine has been turned OFF . The fuel system pressure MUST BE relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

To check the fuel system pressure proceed as follows:

1. Remove the fuel filler cap and relieve the residual fuel pressure. For specific details, refer to the relieving fuel pressure coverage in this section.
2. Attach a suitable fuel pressure gauge to the fuel injection fuel loop as follows:

Models such as the 1998-00 Accord have a fuel pulsation dampener which must be removed in place of the banjo bolt for testing.

1996-97 Accord with 4-cylinder engines and 1996-00 Prelude: Remove the service/banjo bolt from the end of the fuel rail. Install the fuel pressure gauge using a suitable fitting to temporarily substitute for the banjo bolt or in place of the service bolt that will allow fuel to be supplied to the gauge and the fuel rail.

1996-97 Accord with V6 engines: Remove the banjo bolt from the fuel filter outlet and install the pressure gauge using a suitable fitting to temporarily substitute for the banjo bolt and supply fuel to the gauge and the fuel rail.

1998-00 Accord: Remove the fuel pulsation damper from the end of the fuel rail and install a suitable fuel pressure gauge in its place.

3. Remove and plug the vacuum line for the fuel pressure regulator located near the end of the fuel rail.
4. Start the engine and note the fuel pressure. With the pressure regulator vacuum hose disconnected and plugged, the fuel pressure should register as follows:

2.2L engines: 38-46 psi (260-310 kPa)

2.3L engines: 47-54 psi (320-370 kPa)

2.7L engines: 40-47 psi (270-320 kPa)

3.0L engines: 41-48 psi (280-330 kPa)

If the engine won't start, turn on the ignition switch ON, wait two seconds, then turn off the ignition switch OFF. Turn the ignition switch back ON again and read the fuel pressure.

5. If the fuel pressure is higher than specification check for a pinched or restricted fuel return hose or line.

6. If the fuel pressure is lower than the specification check for a damaged fuel pressure regulator, clogged fuel filter, fuel feed line or a leak in the fuel feed line. If the fuel pressure regulator, fuel feed lines, and fuel pump are OK, replace the fuel pump and fuel filter.

The fuel pressure regulator testing procedures are located later in this section.

Once the test is complete, perform the following:

7. Carefully remove the fuel pressure gauge and test fittings.
8. Install the removed fasteners using new sealing washers.
9. Install the fuel filler cap.
10. Start the engine and check for any fuel leaks, and repair as necessary.

1992 Honda Accord will start and idle, but dies on acceleration and when put in gear. Cat is not plugged. New fuel filter installed. Please advise.


Sounds like the fuel pump. Have the fuel pressure checked with a Pressure Test Guage. Different cars have different fuel pressure requirements, but for a fuel injected vehicle should be somewhere in the area of 40-60 psi. Also check that fuel filter was not installed backwards, on some vehicles this can restrict fuel flow,
