SOURCE: 2000 accord no fuel pressure

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

Sounds like the fuel filter. It would indicate the correct pressure at idle or maybe even revving. Once the engine is put under a load (highway speeds) it begins to choke. Try replacing the fuel filter.

Hey have you tried disconnecting and re connecting the battery? my mitsi carisma startd doing that so i rang up dealer and aparently they do it when the computer thinks there is something wrong with the engine, so it enters slow mode (or turtle mode or something) so that minimal damage is done while you drive it slowly to yr mechanic. Could be complettly wrong tho. Good luck.

My 91 honda Accord EX wagon wont start kinda sounds like its not getting gas but has gas in it


So pull a spark plug wire,carefully, and stick a long thin screw driver into the open end, be gentle, hold the screwdriver about a half inch away from the engine valve cover, and have yer buddy crank it ,do you see a blue spark? Ok if you did see the spark, then that system is functioning. If not then its the ignition system. Next at the end of your fuel rail look for the tire valve looking thingy, and turn the key on an then off, take the little plastic cap off of the thingy(Schrader valve) and in the middle of it you see a small pin, push that pin in and if it squirts out fuel with some pressure then you have fuel pressure, if not, check the fuel pump fuse, and the relay, pump.

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.

Car ranning for awhile and then engine dies and it can't be started. Can it be the pickup coil?


This canbe due to many reasons and primarrily the fuel must be checked,Also checck if the fuel pump is good and there is pressure as when the engine heats some pumps can fail to deliver.
Finally check the plugs for the spark intensity, if there is none then the circuit must be checked, check the HT coils, the triggers and the HT wires.
Remove and place the plug outside to check on the spark before you confirm.

My 1996 honda accord consumes too much fuel in a ratio of 1-6 km /liter, what seems to be the problem? I have it tuned up, cleaned the throttles, etc,, but to no avail. whats the best thing to do?


Since you've cleverly already done the normal tune-up items that preserve the 96 Accord's good fuel economy, its time to move onto the tougher adventures.

Cars with outrageously bad fuel consumption are losing fuel somehow (aka leaking).
(a) There's a fuel tank drain plug on the bottom of the fuel tank (used to drain tank for service) - make sure its tight and that the tank isn't leaking fuel there.
(b) check your fuel lines - there are 2 (one supplies fuel to the engine, and the other returns excess to the tank). If either is leaking, your car will lose petrol quickly.
(c) the evaporative fuel canister - instead of absorbing vapours, it may be full of fuel and leaking..
(d) check your fuel rail - its pressurized with fuel while the car is running - it may be leaking - and if it is: (1) the top of your engine will soon catch fire (2) the fuel may be evaporating as soon as it leaks, since the top of the engine gets so hot.

Use a fuel pressure gauge to test the fuel pressure in your 96 Accord's fuel rail - attach your
(with an appropriate (brass) adapter) to where the banjo bolt enters the top of the fuel filter - as
described in this passage from the Honda repair manual:

From the 1996 Honda Accord repair manual:
Note that this part of the Honda manual fails to mention that before you disconnect the negative terminal of the battery, you must note (and write down) the 3-digit radio lock code
--- begin excerpt ---
The Fuel System Pressure Specification


38-46 PSI (Pounds per Square Inch)Remove the ground cable from the negative battery post and also remove the fuel tank filler cap. Slowly release system pressure at the fuel filter and cleanup spilled fuel. Remove the Banjo bolt and install a fuel pressure test gauge. Reconnect the battery ground cable and proceed to start the engine and allow the system pressure to stabilize. While the engine is at idle, block off/pinch the number (1) vacuum line to the fuel pressure regulator and visually verify the fuel pressure reading on the test gauge.
--- end excerpt from 1996 Honda Accord repair guide ---

(e) possible leaking fuel pressure regulator - located at back of top side of engine, and looks like an
enlarged fuel filter - with hose clamps on either end clamping the fuel line. Retighten its bolts to 12 Nm (9 ft-lbs) when done checking it (for leakage).

(f) to move on from fuel - if you're getting only partial ignition, your fuel economy will suffer too - but you'll smell alot of unburned fuel in your exhaust (and get alot of backfiring). Use your HEI (high energy ignition) tester to rule out ignition (spark) problems.

Car not starting altho engine turning over fine and key immobiliser light coming on and going off as normal. my auto boss diagnosis centre said no fault. help


if it is not starting, but turning over, your fuel pump may have gone out, or your fuel filter may be clogged, or fuel lines. My bmw just had a fuel pump go out, put a new one in and voula'. check injection rail there is a little valve like a bicycle tire usually. push it while car is off, there should be some gas spillage or spray so protect your eyes. if there is that means you have pressure and your pump is ok. if not replace fuel pump.

If you have pressure, the next step are your spark plugs and wires . With no fuel there is not ignition, with no ignition, there is no fire.

1995 honda civic d15b7 cranks but wont start. new


Are you sure you have correct timing? its definetly a fule problem, if timing is good then turn your key to the on position and try to listin for the fule pump to prime. While the key is in on position go to fuel rail, there is a valve on fule rail called sharader valve. Get a small screw driver and press valve in to check if car has fule pressure. if pressure is present then it is incorrect timing or possible bad cam sensor.

My 96 blazer wont start it just cranks but wont start?


A typical engine needs mostly just gas and spark to run (besides air of course)
Sounds like the engine is not getting one or the other.

Fuel goes from fuel pump, to filter, to fuel pressure regulator, to fuel rail, to injectors.
You can test for fuel pressure with key on, at the fuel rail. There will be a test port on the rail that you can put a rag on top and push in the valve to see if there is pressure. (or use pressure tester)
If there is no pressure, check that fuel pump relay is working. (you can use an ohmmeter on relay to see if there is resistance). You can also test power to relay and to the pump with a voltmeter to see if pump is getting power. Or turn key to ON position and listen to see if you hear the pump turn on.

If you have no spark to any cylcinders, the crank shaft position sensor may be faulty which is very common in GM vehicles.

You can use an ohmmeter to test the sensor itself.
You can also get a spark plug tester to see if there is spark to each cylinder.
You can also remove one spark plug, plug back into plug wire, lay on top of engine so spark plug diode is 1/4" away from metal surface. Have someone else turn engine over while you look for spark. Do this to each cylinder.

I HAVE HONDA ACCORD 93 AND IT WONT START , CAN


yes it could be the fule filter . You will need to find out if there is fuel going to the injectors this is easy done by removing the inlet pipe to the injector rail and turning the ignition to postion 2 just before cranck. If there is no sign of fule then it couls be your filter .If there is fuel at the injector rail let me no and i will assits further

I suspect fuel pump problem how do I check fuel pressure, what tools do I need


There should be a Schrader valve on the fuel rail (looks like a valve stem on a tire, it is metal).

You need to connect a fuel pressure gauge to that valve and do the following test:

  1. Relieve fuel pressure.
  2. Remove the 12 mm sealing nut from the fuel rail. Attach the fuel pressure adapter nut, 12 mm (90201 - P0A - 003) and the special tool.
  3. Start the engine. Measure the fuel pressure with the engine idling and the vacuum hose of the fuel pressure regulator disconnected from the fuel pressure regulator and pinched. If the engine will not start, turn the ignition switch on, wait for two seconds, turn it off, then back on again and read the fuel pressure. Pressure should be: 260 - 310 kPa (2.7 - 3.2 kgf/sq.cm, 38 - 48 psi)
  4. Reconnect vacuum hose to the fuel pressure regulator. Pressure should be: 210 - 250 kPa (2.1 - 2.8 kgf/sq.cm, 30 - 37 psi) If the fuel pressure is not as specified, first check the fuel pump. If the fuel pump is OK, check the following:
    • If the fuel pressure is higher than specified, inspect for:
    • Pinched or clogged fuel return hose or line.
    • Faulty fuel pressure regulator.
    • If the fuel pressure is lower than specified, inspect for:
    • Clogged fuel filter.
    • Faulty fuel pressure regulator.
    • Fuel line leakage.
