Question about 2000 Subaru Legacy

5 Answers

Hard start condition after maintenence

I just recently replaced the fuel filter, cleaned the k&n air filter, and gave my 2000 Subaru Legacy Outback wagon, and afterwards the car has trouble starting. The car started just fine before I performed the repairs mentioned above but afterwards the car has trouble starting, mainly when the engine is cold. The fuel hoses to the fuel filter were bad so I replaced them with high pressure hose, but other than that nothing else was changed. Once the car starts it runs just fine and actually has excellent power. What could be causing my problem? Any ideas are appreciated.

    I never said the car would not crank, but that it takes more time than before for the car to fire up than it did before I replaced the parts. It cranks but not fire like it did.

  • mjmanter Aug 13, 2008

    The solution did not even cover the problem. I never even said anything about the car not cranking at all.

    There was a little hose that popped off the air intake. I pushed it back on & the car started up with no problems. Thanks!

Make sure your installation of the fuel filter is correct. I had the same problem with a truck and it turned out to be a poor installation (mine) of the fuel filter. Just a thought. Good luck

It cranks at the same speed, correct? Sounds like the fuel isn't getting to the engine as quick as it used to, but once it does it runs fine. By increasing the pressure, it takes more to get the fuel to the engine. Try to turn the key to on, not start and let it sit for 5-10 seconds and then crank and see if it starts right away. It may just need time for the fuel to get to the engine. Getting a better fuel pump may also improve the time that it takes to start.

Hi...
If you said before you replace the Fuel Filter and clean the Air filter. K&N. Performance filter.
First Check the Position of the filter. IN and OUT.
Be sure the "Out" is in direction of the Engine
And" IN " in direction to the Fuel tank.
Check if the Hoses that you have replaced.
Check if the hose is not too bent. making restriction in the Fuel pressure.
Careful Check if there any fuel leak on the Hoses.
cHeck if there any leak on the tube from the Air filter to the Throttle Body.
But is good Idea to check the Sparkplug, And replace if need.

I hope this help to try solve your problem.

Thank.... GUILL......

Check Your Fuses: Few cars have a fuse associated with the starting system, but before you go monkeying around with everything, check your fuses to be sure it's not that simple.

Battery Corrosion: Over time your battery connections can become dirty, or corroded. This corrosion breaks the connection your battery has with the rest of the car, and it won't start. Try cleaning your battery posts and try to start the car again.

Dead Battery: The most common reason your car won't start is a dead battery. If you have a battery tester that can measure cranking amps, test your battery to see if it's weak. If you can't test it yourself, you can test the battery indirectly by jump-starting the car. If it starts right away, your problem is most likely a dead battery. Replace the battery, and clean the battery connections to ensure good contact.

Bad Igntion Switch: If your battery checks out, but the starter is still silent, it may be a faulty ignition switch. Turn the key to the on position (not all the way to start). If the red warning lights on your dash don't light up (and your battery connections are clean), the ignition switch is bad. If they do light up, turn the key to the start position. The dash warning lights should turn off at this key position (most cars). If you're not sure, turn on the headlights. When you try to start the car, the lights should either dim (a lot) or turn off completely. If they do, your ignition switch should be ok. If not, the switch will need replacement.

Bad Starter Connection:
Corrosion can not only keep your battery from connecting, it can affect any electrical component, especially the ones exposed to the elements like the starter. If you have a helper, you can test the connection by holding a circuit tester lead on the wire that engages the starter. This is the smaller of the two wires connected to the starter.

Where to is the fuel filter for legacy outback H6 3.0 2001 model


the fuel filter is marked in the box.
first mark each hose with a different mark. then simply remove the clamps and carefully pry off each hose connection.
if the hose is damaged 5/8" fuel hose can be used to replace pieces if necessary due to drying out rubber

Loping idle with a '98 Subauru 2.5


This usually happens when the fuel pump is loosing pressure.

I will just advice you make a replacement on the fuel pump. It is located in the fuel tank beneath the back seat.

Be sure to consider the rating on the fuel pump when replacing.

Good luck and rate my solution.

2000 Subaru Outback wont start.. no fuel.


Are your injectors firing into the engine? You can buy a test kit to double check that. Is there spark at the plugs?

I had the same problem sorta with my civic it turns out after doing timing belt water pump, and many gaskets i had a huge vaccum leak.

Also check your fuel lines to see if they are loosing pressure somewhere
