What's your question? Replaced timing belt on 2001 dodge stratus 2.4 liter and still wont start

Have you checked for spark on a plug wire with the engine cranking? If no spark, the problem is in the ignition system- the ignition coils, the ignition control module, the plug wires and plugs, the crankshaft position sensor, and the PCM-all are parts of the ignition system. Don't replace without testing- it will save you money.

Also check the fuel pressure at the engine, or at least verify the fuel pump is getting gas up to the engine. If you turn the key to on, not start, the fuel pump should turn on for 2 seconds to put pressure in the line and in the fuel rail where the fuel injectors are. Do you see a valve on the fuel rail, it may have a cap screwed on it. This is the test port to hook up a fuel pressure gauge and check fuel pressure. Autozone and others loan or rent fuel pressure gauges.

Have a gauge hooked up to low pressure fuel pump and it shows it works but high presssure one doesnt

Check to see you have oil up to full on dipstick . The high pressure pump picks up oil at the top level so if oil starts to get to low engine will stop before engine damage . The high pressure pump is what makes the injectors fire . Also check the wires that go thru valve cover some times they burn up and you can smell the burn thru the oil filler cap .

How can i get to the fuel pump on a 92 acura vigor?

  • Print
    The fuel pump on all models except the 1986-90 Integra, is located in the fuel tank. On the 1986-90 Integra the fuel pump is located under the rear of the vehicle, near the drivers side of the fuel tank.


    See Figure 1
    On all models, the fuel pump should run for about 2 seconds when the ignition is first turned ON . By removing the filler cap and listening at the filler, it should be possible to hear the pump run each time the ignition is switched ON . It will then stop again until the starter is activated.

    Fig. Fig. 1: Checking the fuel system pressure

    1. Disconnect the negative battery cable and remove the fuel filler cap.
    2. Relieve the fuel system pressure.
    3. Remove the service bolt and attach a fuel pressure gauge to the top of the fuel filter.
    4. Start the engine and measure the fuel pressure with the engine idling and vacuum hose to the pressure regulator disconnected;

    1986-1989 Integra-35-41 psi. (240-279 kPa) 1990-93 Integra-37-44 psi. (255-304 kPa) 1989-90 Legend-36-41 psi. (250-279 kPa) 1991-93 Legend-38-46 psi. (265-314 kPa) Vigor-43-50 psi. (300-350 kPa)
    1. Check to see that the pressure decreases when the vacuum hose is connected.
    2. If the pressure is higher than specifications, check for a pinched or clogged fuel return hose or faulty pressure regulator.
    3. If the pressure is lower than specifications, check for a clogged filter, defective pressure regulator or leakage in the fuel line.
    4. After inspection, remove the pressure gauge and install the service bolt with a new washer.


    1986-1989 Integra

    1. Disconnect the negative battery cable.

    I have a 1997 chevy tahoe 4x4 how do i change the fuel pump?

  • Disconnect the cable to the battery's negative terminal with a socket wrench. Loosen the filler cap on the fuel tank to relieve the pressure in the fuel tank. Drain the fuel tank by siphoning the fuel into a gasoline container with a hose. Raise the rear of the vehicle with a jack and support it on jack stands. Release the clamps on the hoses for the filler neck and vent tube of the fuel tank. Support the fuel tank with jack stands and detach the support straps for the fuel tank. Lower the fuel tank slightly and disconnect the electrical connections and hose on the fuel tank. Remove the fuel tank from the vehicle.

  • Turn the retaining ring on the fuel sender assembly counterclockwise with tool . Remove the retaining ring. Lift the fuel sender assembly out of the fuel tank and pull the fuel pump into the attaching hose while holding the bottom support of the fuel pump in place. Discard the O-ring on the fuel tank.
  • Install the new fuel pump into the attaching hose of the fuel sender assembly. Use care to avoid bending the fuel strainer since this will restrict fuel flow. Place a new O-ring on the fuel tank and install the fuel sender assembly into the fuel tank.

  • Place the locking ring on the fuel sender assembly and turn it clockwise with tool until the ring locks into place.

  • Install the fuel tank by reversing step 1. Pressurize the fuel system by turning the ignition on for two seconds and turning it off for 10 seconds. Turn the ignition on and check the fuel lines for leaks.

    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.


    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.

    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.

    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.

    Wont idle or start without priming tbi

    first check fuel pressure with a mechanical fuel gauge that attaches to fuel line schrader valve. around T.B.I. if no pressure with key on check fuel pump relay for correct operation, and also the oil pressure switch has the fuel circuit to it so possible oil pressure switch also. fuel pump has a check valve to keep fuel from going back to tank, so when u turn key on fuel pressure should go up within 1-2 seconds on gauge. if fuel pressure goes down quickly, possible bad fuel check valve, change fuel pump and fuel pump check valve (located right above fuel pump inside tank)

    Is there an access hatch in the floor of a 1996 gmc safari for the fuel pump

    no, sorry. Here are the R&R instructions from

    The following procedure requires the use of the GM Fuel Gauge Sending Unit Retaining Cam tool No. J-24187 or equivalent.

    CAUTION Before removing any component of the fuel system, be sure to reduce the fuel pressure in the system. The pressure regulator contains an orifice in the fuel system; when the engine is turned Off, the pressure in the system will bleed down within a few minutes.

    1. If the fuel system has been in use, turn the ignition switch to OFF and allow the system time to reduce the fuel pressure.
    2. Disconnect the negative battery terminal from the battery.

    Be sure to keep a Class B (dry chemical) fire extinguisher nearby.

    CAUTION Due to the possibility of fire or explosion, never drain or store gasoline in an open container.

    1. Using a hand pump or a siphon hose, drain the gasoline into an approved container.
    2. Raise and support the vehicle on jackstands.
    3. Support the fuel tank and remove the fuel tank-to-vehicle straps.
    4. Lower the tank slightly, then remove the sender unit wires, the hoses and the ground strap.
    5. Remove the fuel tank from the vehicle.
    6. Using the GM Fuel Gauge Sending Unit Retaining Cam tool No. J-24187 (or equivalent) or a brass drift and a hammer, remove the cam locking ring (fuel sending unit) counterclockwise, then lift the sending unit from the fuel tank.
    7. Remove the fuel pump from the fuel sending unit, by performing the following procedures:
      1. Pull the fuel pump up into the mounting tube, while pulling outward (away) from the bottom support.

    When removing the fuel pump from the sending unit, be careful not to damage the rubber insulator and the strainer.
      1. When the pump assembly is clear of the bottom support, pull it out of the rubber connector.

    To install:
    1. Inspect the fuel pump hose and bottom sound insulator for signs of deterioration, then replace it, if necessary.
    2. Push the fuel pump onto the sending tube.
    3. Using a new sending unit-to-fuel tank O-ring, install the sending unit into the fuel tank.

    When installing the sending unit, be careful not to fold or twist the fuel strainer, for it will restrict the fuel flow.
    1. Using the GM Fuel Gauge Sending Unit Retaining Cam tool No. J-24187 (or equivalent) or a brass drift and a hammer, turn the sending unit-to-fuel tank locking ring clockwise.
    2. Install the fuel tank, align the insulator strips and install the strap bolts. Torque the inner fuel tank strap-to-vehicle bolts to 26 ft. lbs. (35 Nm) and the outer fuel tank strap-to-vehicle nuts/bolts to 26 ft. lbs. (35 Nm).
    3. Connect the fuel lines.
    4. Connect the negative battery cable, start the engine and check for leaks.
    5. Lower the vehicle.
