Question about 2000 Subaru Legacy

1 Answer

2000 legacy sudden loss of power

2000 legacy runs fine for awhile, suddenly seems fuel starved and I have to barely give it gas to keep running at a much slower speed. Parked the car with engine running and noticed a sucking and clicking sound coming from the right rear wheel-well area, where the fuel tank is located so possibly a sound from the fuel pump mechanism? A diagnostic code tool I borrowed from Auto Zone indicated a possible sensor problem. Could a sensor problem cause the fuel pump to malfunction and the sucking clicking sounds? Also noted that turning the engine off and restarting the car seems to immediately clear the problem for awhile.Happens after driving 20 minutes or so it's kinda like a vapor lock except the car barely keeps running.

I'm not sure which sensor your referring to but the fuel pump & regulator are located in the tank. Did anything bang into the car or tank causing it to be on an angle? Get fuel PSI reading while running & stall & go from there. Where is this suction/clicking sound coming from?

SOURCE: center differential

What you are discribing sure sounds like CV (constant volocity) joint noise from the axle(s), diff's don't make crunching noises, they whine and howl when they go bad, I will say this about your problem, you did not have it before the work was done, so it's a fair guess it has something to do with the work done, make them fix it, do you agree?

Check The Vehicle Speed Sensors.

The Legacy has 2 Vehicle Speed Sensors (VSS): VSS1 is located inside of the transaxle; VSS2 is located in the combination meter assembly.

VSS1

  1. Disconnect the electrical harness from the transaxle.
  2. Connect an ohmmeter across the transaxle's electrical harness terminals 9 and 16.
  3. The resistance should be 450-650 ohms.
  4. After testing, reconnect the electrical harness.
VSS2
  1. Remove the instrument cluster from the instrument panel.
  2. Disconnect the electrical connectors and the speedometer cable from the instrument cluster.
  3. Connect an ohmmeter or continuity tester across the combination meter terminals 7 and 11.
  4. Insert a small screwdriver in the speedometer cable drive socket.
  5. Rotate the speedometer drive and note the continuity across the VSS terminal. Continuity should turn ON/OFF 4 times per speedometer drive revolution.

SOURCE: How do you replace the fuel pump in 1992 2wd Subaru Legacy Wagon

  1. Relieve the fuel system pressure.
  2. Disconnect the negative battery cable.
  3. Remove the rear exhaust pipe and muffler assembly.
  4. On All Wheel Drive (AWD) vehicles, remove the rear differential assembly and the rear crossmember. You do not have AWD so this step is not for you
  5. Remove the fuel filler cap and drain the fuel into a suitable container.
  6. Remove the fuel filler pipe protector.
  7. Raise and support the vehicle safely on jackstands.
  8. Remove the fuel filler, air vent and delivery hoses.
  9. On AWD vehicles, disconnect the air breather hoses and evaporation hose from the pipes.
  10. Support the fuel tank with a floor jack or equivalent lifting device.
  11. Loosen the attaching bolts and lower the fuel tank slightly.
  12. Disconnect the fuel pump harness

SOURCE: will the knock sensor make any difference to the way the car runs? it has a crack in it.

Your car is not OBD-II, some dealers still have the Subaru Select Monitor required, some haven't kept them. Your local mechanic is unlikely to have spent $2,000 for a tool that only works on 15 to 20 year old Subarus. You can read the check engine light codes without any special tools though, see http://legacycentral.org/library/literature/codes.htm

The fuel filter is right next to the windshield washer fluid tank.

Perhaps it's a stuck carburetor float valve, bad fuel pump (if it has one) or clogged fuel filter.

Fuel delivery problem, not enough fuel on acceleration could cause backfires. Many things cause backfires, mechanical and electronic. I need more info to give a better diagnosis. Did the problem happen all of a sudden or has the vehicle been running crappy for awhile.

Runs good until you accelerate then it lacks power it dont miss just alarge power loss in every gear if you let off of the gas its power comes back its about to drive me crazy please help? dwb


I would suggest changing the fuel filter. The engine seems to be starving for fuel and if the filter is pulgged, the engine will bog down under load. Then the engine will run better when coasting because the fuel pressure will build up again.

You will need to check the fuel pressure, if it is on the minimum pressure side or lower then you will need to change the fuel pump.

2000 jeep cherokee sport 4.0 dies want idle


This has happened all of a sudden?
It is sounding like it is starving for fuel...

First we will check for bad fuel. A GOOD Gasline Antifreeze can get the impurities and water out of the Gas. Get a bottle and pour the whole thing in the gas tank, bounce the car around to mix it with the fuel. Start it and let it run for a little while so see if it smooths out. If does not help then look at replacing the fuel filter as it may be clogged.
