In the fuel tank and you have to remove it

    That fuel pump is located under the hood, driver's side, atop the wheel well; it looks like a black, metal box. You can locate and remove the fuel line from it to check whether your fuel pump is pumping; but, not necessarily check for the correct pressure.

03 subaru Legacy 2.5 won't start . Turns over but won't fire. I have replaced fuel pump , fuel filter , and the pressure regulator. Pure fuel in the intake and starts fine What could be the problem

Does it start and keep running? Or does it start and just run for a few seconds? If it starts and runs for a few seconds you need to check your fuses first. It could be the fuel pump or EFI fuse or a few others.
If you prime it and it keeps running, well, you've got me there.

94 subaru legacy wagon will start and run for a few seconds if the fuel pump is disconnected but won't start at all when reconneced.

Check for a very dirty air filter or an obstruction in the air intake. (Engine not getting enough air so mixture is too rich.) Check for fuel pressure to be correct and not too high with the pump running. If it is too high, check that the fuel pressure regulator is working.

Try this: connect the fuel pump but disconnect the cold start fuel injector. If you can get it to start and run, then fuel pressure being too high is most likely. When the cold start injector turns on, the extra pressure is causing more fuel to flow through the injector than normal and the engine floods out.

1991 legacy died. daughters car on highway and the motor just quite at high speed. Dash lights all came on, motor turns over but will not start. It is in a remote location. I am going to take parts...

First you should see what is missing. What I mean is before you start changing parts. Check your basics. Check for fuel pressure, check for spark, check compression. After you determine what is missing then start troubleshooting that prblem, for example if you did nothave proper fuel pressure then, yes, you could have a bad fuel pump or simply a clogged fuel filter. But find out what your missing first then find out your cause of the problem.

1991 subaru legacy turns over but will not start check every on it has spark and fuel. driving it one day it as running then just died? so can u help me please.

Possibly the timing belt is broken. How does the engine sound when you crank the starter. Does it sound "normal" or does it sound fast and quiet? Have someone else crank the starter, can you feel any pressure coming out of the tailpipe? If the timing belt is broken the engine will sound very quiet and there will be no pressure coming out the tailpipe.

Do 1991 L series subaru legacy wagons have adjustable valves?

This model does not and uses a hydrallic lash adjuster that works something like the old lifters did. Generally when these collapse or lose hydrallic pressure,a rattling occurs in the valve train. Most generally this is a sign of an oil pressure deficit and may require a new oil pump then hopefully all lash adjusters will pump back up and close the rocker to valve clearance stopping the rattle.

Engine seems to run good then goes downhill

Have a look at the fuel pump it looses pressure when hot which means it is due to be replaced.

1991 subaru legacy. The car would not start. I change the fuel filter and tapped on the fuel pump. It started. A few days later same thing. Tapped on the fuel, worked again. A few days later same thing....

You should have a fuse & a relay. Check # 11 fuse it should be 15 amp.& may be for your fuel pump. Do you have owners manual by chance, or does cover of fuses have label?
