Question about 1997 Honda Passport

1 Answer

How to install a new fuel pump in my 1998 Honda Passport? How to test if it's the fuel pump, fuel pressure regulator or the fuel sending unit that's causing the problem. Problem: When I start my truck, it turns over but stalls out immediately. It takes more and more starts to get it going, I've had it die out on me while driving twice...but this is over a 1 month period. Sometimes the gas guage will show and empty tank when I know there is gas in the tank (happening for about 6 months).

The gas gauge contacts get corroded by the chemicals in your gasoline over time, the only way to fix that is to replace the fuel sender unit...unfortunately the sender unit is usually incorporated into the fuel pump. fuel delivery problems like you describe could be clogged or dirty fuel injectors...if it's dying out on you as you drive it probably is indeed the fuel pump...usually an expensive fix. try an auto wrecker to find one for about 100 bucks.

    usually an internal fuel pump is not too tough to change, you will have to drain the tank, undo all connections to the fuel pump, undo the bands holding the tank up, lower the tank to the ground, and the fuel pump should be bolted into the top of the tank. remove the bolts and lift out the pump. reverse for reinstallation.

These Isuzu-built vehicles had many problems with fuel system components. Particularly the sending unit in the tank. Note: If the unit is replaced, the PCM must be updated to accept the new pump calibration before it will work.

2001 honda passport not getting fuel


First off, do you hear the fuel pump priming when you turn on the key. Should hear a light buzzing from the fuel tank for approx. 5 seconds. Have you opened the pressure line or the pressure test port on the fuel line on top of the engine to see if you are getting any fuel even trickling out especially during the priming. Pressure should be in the neighborhood of 45-50 psi for the system. A fuel pump can slowly fail, by losing pressure, but still can move some fuel if you hear it running oon the prime cycle. You can often borrow a fuel pressure guage from your local chain auto parts store to actually see what's goin on with the fuel system. You hook it up to the test port on the fuel rail and watch the pressure on the prime cycle. If it is very low, try priming the system 3 or 4 times to see if pressure builds, if not that would lead to testing the pressure regulator. But that's for next time.

I had the same problem with my Passport and it was the fuel pump going bad. The pump was not producing enough pressure to get the fuel into the fuel system. A local shop discovered the problem when they did a pressure test on my fuel system.

Dash gas gage shows empty car runs fine previous owner put new fuel pump in it


Sounds like the fuel tank sender unit is faulty; keep in midn that the Passport fuel gauges can be calibrated, and won't work properly when out of calibration. Your local Honda dealer has the tools to calibrate the sending unit/fuel gauge assembly. That's the first thing to try, after that if there is still a problem you may have an issue with the sending unit itself or the fuel gauge on the dash.

Hope this helps (remember to rate and comment this answer).

2000 Malibu Starts then looses fuel pressure I have replaced the fuel pump and the fuel pump relay still same problem


Keep in mind that you have several components there:
- Fuel Pump Sender Assembly,
- Fuel Pressure Regulator,
- Fuel Rail Assembly, and
- Fuel Injectors.

1.- Fuel Pump (Sender Assembly) - TESTING
Refer to the accompanying charts for fuel pump diagnosis and testing.

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.

Fuel Pressure Regulator - REMOVAL & INSTALLATION

(the fuel pressure regulator, which is located on the fuel rail assembly)

NOTE:
Before removing the fuel regulator assembly, place a clean shop towel under the regulator to catch any fuel drips

  1. Properly relieve the fuel system pressure.
  2. If not done already, disconnect the negative battery cable.
  3. On the 3.1L engine, remove the intake manifold plenum, as outlined in .
  4. On the 2.4L engine, remove the fuel rail. Refer to procedure earlier in this section.
  5. Detach the vacuum line from the regulator.
  6. Place a shop towel under the regulator to catch any fuel that may drip out. Unfasten the fuel pressure regulator retaining screw, then remove the regulator by twisting and pulling it from the fuel rail.
  7. Remove and discard the O-ring seal. Inspect the filter screen for contamination and replace if necessary.
To install:
  1. Prior to assembling the pressure regulator to the fuel rail, lubricate the new rail-to-regulator O-ring seal with clean engine oil.
  2. Place the O-ring on the pressure regulator and install the pressure regulator to the fuel rail.
  3. Install the retainer or coat the regulator mounting screws with an approved thread locking compound and secure the pressure regulator in place. Tighten the mounting screw to 76 inch lbs. (8.5 Nm).
  4. If removed, install the fuel rail assembly to the engine.
WARNING The fuel return pipe must be connected before tightening the regulator retaining screw to prevent the regulator from rotating. Rotation of the regulator could damage the retainer and spacer bracket and lead to a fuel leak at the regulator inlet.
  1. Connect the fuel feed line and return line to the fuel rail assembly, use a backup wrench on the fittings to prevent turning.
  2. Attach the vacuum line to the regulator.
  3. On the 3.1L engine, install the intake manifold plenum.
  4. Connect the negative battery cable. Turn the ignition to the ON position for two seconds, then turn it to the OFF position for ten seconds. Turn again to the ON position and check for fuel leaks.

Fuel Pump - Removal & Installation
The in-tank fuel pump module contains the fuel pump and pressure regulator which adjusts fuel system pressure. Fuel pump voltage is supplied through the fuel pump relay.

The fuel pump is serviced as part of the fuel pump module. The fuel pump module is installed in the top of the fuel tank and contains the electric fuel pump, fuel pump reservoir, inlet strainer fuel gauge sending unit, fuel supply and return line connections and the pressure regulator. The inlet strainer, fuel pressure regulator and level sensor are the only serviceable items. If the fuel pump requires service, replace the fuel pump module.
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Properly relieve the fuel system pressure.
  3. Remove or disconnect the following:
    Negative battery cable Fuel tank

  6. Remove the fuel pump and O-ring from the tank and discard the O-ring.
To install:
  1. Thoroughly clean all parts. Wipe the seal area of the tank clean. Place a new O-ring on the ledge between the tank threads and the pump module opening.
  2. Position the fuel pump module in the tank. Be sure the alignment tab on the underside of the pump module flange sits in the corresponding notch in the fuel tank.
  3. While holding the fuel pump module in place install the locking ring and torque to 40 inch lbs. (5 Nm) using special tool 6856 or a spanner-type tool.
  4. Install or connect the following:
    Fuel tank Fuel pump module electrical connector Negative battery cable
  5. Fill the fuel tank with fuel. Install the fuel filler cap. Turn the ignition switch to the ON position to pressurize the system. Check the fuel system for leaks.

Fuel pressure regulator location on a 2002 Dodge Caravan .The van stalls when trying to slow down or comming to a stop.


The regulator is in the fuel tank. You must drop the tank to get to the system It is part of the fuel pump/fuel pressure regulator/fuel level sending unit. If just changing the regulator which you can,make sure you install new o-rings, put a little clean gas on them to install. Cheaper than a new fuel pump.

The problem is most certainly the fuel level sending unit - not the fuel pump. However the mechanic was right in a sense that if you're going to pay the labor cost to drain and purge the gas tank to replace the sending unit you might as well replace the pump at the same time, since you have to take it off to get to the real problem.

Use your odometer.

your sending unit in the gas tank is bad. You most likely already priced a new one that you can only get with a fuel pump. {around 275-300 dolllars}. I found the sending unit by itself on ebay for around 40 dollars. Just go to ebay and type in 98 99 00 01 02 rodeo passport fuel sending unit and that should take you to the guy I'm getting mine from.
