Question about 2000 Subaru Legacy
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?

The codes, you can read.
You can see two plugs, they are pars. One pars of colours green and the other black or white.
you sure the ignition off , Plugs green colours plug them together, attention, only the green and turn ignition but dont start motor. The check engine ligth will flash, the flash long are numbers 10, the flash short are numbers 1.
Example: the check engine ligth flash long 2 times, the code is 20
or flash long 3 times and flash short 4 times the code is 34.
What code it is ??
He comes some codes.

You sure the finshed job unplugged the plug green

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.

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.
