Question about 2002 Chrysler Concorde

2 Answers

2002 Concord wont start

Fuel pump runs and pumps fuel with some pressure at the first connection after the tank. There is no fuel in the return line though.
I squirted starting fluid into a vacume line opening in the air plenum and the engine acted like it was going to start but didn't quite get there. Thanks

    How is the inertia switch reset? I have not changed the fuel pump yet.

  • jimv3113 Jun 04, 2009

    Do I need to remove the plenum to get to the fuel rail and injectors?

You need to see how much fuel presure is getting to the fuel rail. the filter is built in the pump it self.

fuel pressure should be around 58 psi. if the pressure is not correct you need to check the fuel lines for a restriction. if thats ok you will need to replace fuel pump do to a weak motor.I have had both problem on this car. the last one was a blocked line.also need to see if the injectors are powering up. you can check with a noid light. a test light will work in some cases. I guess your getting fire to the spark plugs if you have not checked thayt you need to do this also.in order to check the injectors you will need to diconnect the connector and crank engine the light will flash as long as you crank it. let me know if all this is good or not and we can go from there.thanks.

    there is no inertia switch on a chrysler. whitch engine do you have so i can tell you about the fuel rail.chryslers are a little harder to test the pressure do to they do not give a good access to the lines.I will recheck my mail shortly for your reply.

Hi,

You will only have 12 volts to the pump when the engine is either cranking or running. It is not unusual for a fuel pump to test good after it has been removed from the tank due to the jarring when it is removed. However, when the fuel pump is replaced, it is likely that it failed to start. Check the relay and a fuse just to be sure.

Try resetting the fuel pump inertia switch. If there is 12 volts at the pump and there is no fuel pump pressure, then the pump has failed and need to be replaced. Sometimes repairs are not related but fail at the same time, bad luck.
If the fuel pump you installed was not OEM original equipment manufacture, that is the problem. The fuel pressure it takes to run you vehicle depends on 60 psi fuel pressure constant. Inexpensive fuel pumps are that way for a reason, there are not as good and cannot hold pressure. Replace fuel pump with OEM fuel pump to repair problem. Also Sounds like you have contamination in your gas tank that is shortening the life of your fuel pump. Remove fuel tank to flush as needed. Reassemble to recheck.

Thanks for contacting Fixya.

You should have a test port on the Fuel Supply rail, use a tool from a local auto parts "Tool Loaner program" where you can borrow tools for free,w/a deposit of course,then follow the steps provided;

MPI Fuel System Pressure Test

The MPI fuel system used in vehicles equipped with a 4.OL engine employs a vacuum balanced pressure regulator. Fuel pressure should be approximately 55-69 kPa (8-10 psi) lower with the vacuum line attached to the regulator than with the vacuum line disconnected. System fuel should be 214 kPa (31 psi) with the vacuum line connected to the regulator and 269 kPa (39 psi) with the vacuum line disconnected. CAUTION: Some fuel may be discharged when connecting fuel gauge to fuel rail.
  1. Connect a 0-414 kPa (0-60 psi) fuel pressure gauge to test port pressure fitting on fuel rail (Fig. 7).
  2. Remove vacuum line from pressure regulator.
  3. Start the vehicle.
  4. Note gauge reading. With vacuum line disconnected, fuel pressure should be approximately 269 kPa (39 psi).
  5. Connect vacuum line to pressure regulator. Note gauge reading. Fuel pressure should be approximately 214 kPa (31 psi).
  6. If fuel pressure is not approximately 55-69 kPa (8-10 psi) higher with vacuum line removed from regulator, inspect pressure regulator vacuum line for leaks, kinks or blockage. CAUTION: Fuel pressure will rise to as much as 655 kPa (95 psi) when the fuel return tine is pinched shut, shut engine down immediately after pinching oft fuel return line.
  7. If fuel pressure is low, momentarily pinch shut the hose section of the fuel return line. If fuel pressure remains low, inspect the fuel supply line, fuel filter, and fuel rail inlet for blockage. If fuel pressure rises replace fuel pressure regulator.
  8. If fuel pressure is above specifications, inspect the fuel return line for kinks and blockage.

Capacity Test

  1. Remove the cap from the pressure test port in the fuel rail.
  2. Connect a 0-414 kPa (0-60 psi) fuel pressure gauge to the pressure fitting on the fuel rail (Fig. 7).
  3. Start the vehicle. Pressure should be approxi- mately 214 kPa (31 psi) with the vacuum hose connected to the pressure regulator and 269 kPa (39 psi) with the vacuum hose removed from the pressure regulator.
  4. If the pressure is not to specification, check the following before replacing the fuel pressure regulator:
  • 4a - Inspect the fuel supply and return lines/hoses for kinks or restricting bends
  • 4b - Check the fuel pump flow rate. A good fuel pump will deliver at least 1 liter of fuel per minute with the fuel return line pinched off. If the fuel pump does not pump adequately, then inspect the fuel system for a plugged fuel filter or fuel pump inlet filter (sock). Fuel pump flow rate can be done by connecting one end of an old A/C gauge hose to the fuel test port on the fuel rail and inserting the other end of the hose into a container of at least 1 liter capacity. Run the fuel pump by installing a jumper wire into diagnostic connector terminals D1-5 and D1-6. Be sure to pinch off the fuel return line or most of the fuel will be returned to the fuel tank.

Do i have to drop the tank to replace a fuel pump on a 2002 montero sport


WARNING In almost every case, replacing the Mitsubishi electric fuel pump requires removal of the fuel tank. Please refer to the fuel tank removal and installation procedure at the end of this section.
  1. Lift or move aside the carpet in the rear cargo area.
  2. Remove the oval cover plate from the access hole.
  3. Disconnect the fuel pump harness connector at the rear of the fuel tank.
  4. Start the engine, allowing it to run until it runs out of fuel. This relieves pressure within the fuel system.
  5. Turn the ignition switch OFF and disconnect the negative battery cable.
  6. Remove the fuel filler cap.
  7. Drain the fuel from the fuel tank into suitable container(s), each with an airtight lid.
  8. Carefully, and using two wrenches on the fittings, disconnect the high pressure fuel line and the main fuel line from the pump. Remove the high pressure fuel hose at the body-side main pipe connection, unfasten the pump-side connection. Wrap each joint in a rag before loosening; some pressure may remain within the system.
  9. Remove the fuel pump retaining nuts and carefully remove the pump from the tank.
The fuel pump may still contain liquid fuel. Drain it into a suitable container with an airtight lid before performing any tests or inspections.
To install:
  1. Carefully install the pump into the tank and install the 6 retaining nuts onto the studs. Tighten the nuts evenly and in a crisscross pattern to 12 ft. lbs. (16 Nm).
  2. Reinstall the high pressure and supply line to the pump.
WARNING Take great care when connecting the threaded high pressure lines. Start the threads by hand, then, while holding the hose side to keep it from turning, tighten the flare nut to 27 ft. lbs. (37 Nm).
  1. Connect the pump wiring harness.
  2. Connect the negative battery cable. Turn the ignition key to ON but do not start the engine. You should hear the pump running. Allow it to run for about 10 seconds to build line pressure, then start the engine.
  3. After the engine has run smoothly for a minute or two, shut the ignition off and check the work area for any trace of leakage. Attend to any fuel leaks immediately, remembering that the system has repressurized and must be handled safely.
  4. Reinstall the cover on the access hole and replace the carpet in the cargo area.

You should be able to hear the fuel pump, With the key in ignition turn to the ACC position do you hear a humming noise. If no then you need a fuel pump , If yes then youll need to troubleshoot other area of concern

Replaced the fuel pump fuel filter , no start in my 95 S10 Blazer. add gas will run, untill the gas stops pouring in by hand . new part on top of the throtle body as well, i think it controls th O2 and...


1. Does the pump actually run (key on engine off) pump should run for 2 seconds and go off and can be heard if you listen at the filler neck with the gas cap removed)
pump not running - Check relay (replace if bad) check wiring/fusese

Pump runs... go on to #2...

2. check the gas guage. is the gauge reading in the normal area it would read in or is it way way off like WAY above full or way below empty? This is a sign the electrical connection at the pump is plugged in backwards and the pump is spinning the wrong way and not picking up the fuel... (This is easy to get plugged in backwards inside the tank when installing the new pump)

3. Check for feed, return and vent lines being installed wrong where they attach to the tank... they can easily be hooked up wrong and fuel is either pumped up in to the return line or pumped in to the fuel tank vent line..

4. check for kinked or crushed fuel lines from tank to engine.

5. check fuel pressure regulator to be sure its not stuck open.

Fuel delivery problem


Was the pressure relief valve checked?Try crimping without damaging the fuel return line ,Get somebody to try to start the vehicle while you do this, if it trys to start either the pump has failed again or the fuel is bypassing and being returned to the fuel tank.How long before replacement of pump and breakdown? Did they tell you what pressure it was supposed to be at.I have seen an ignition module give very similar symptoms.
