Question about 2006 Subaru Outback
2006 Subaru Outback 2.5i with 115,000 miles. Hesitation on Startup. Fuel related (pump)? Spark plugs? Battery & Alternator checked out fine with multimeter. Spark plugs haven't been changed since 50,000 miles. Timing belt changed at 100,000 miles. Any ideas?
If you are saying it takes a long time to start the engine, have you checked fuel pressure before and after cranking ?

The 2.5L engine has a timing belt and it should be replaced at 105K. The 3.0L engines have a timing chain and are not serviced regularly.

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

This is not your average timing belt replacement due to being a double overhead cam that is also an interferance fit.First remove cooling fans.2-Loosen drive belts and remove.3-Remove crank pully.4-Remove timing covers.You will see 4 cam sprockets.Theses sprockets contain single and double referance marks.You will be using the double referance marks.Rotate engine until the double referance marks are facing each other.This is to be done the same way that the American autos timing Chain systems are done but you will have 2 small double lines to line up not dots.The next step is the most important step and is of utmost imortance.THE CAMSHAFT HAVE TO BE LOCKED IN PLACE--FAILURE TO DO SO CAN RESULT IN BENT VALVES.The cam sprocket holders can be bought or rented.You can make your own as well by making 2 wedges with bolt through the middle.Slip in between sprockets and tighten enough to hold sprockets.Do not use excessive torque while tightening wedges sprockets are not made of steel but rather a composite material.Next you will have to remove the tenioner.The tensioner has to be retracted and pin istalled to hold in retracted position.The tension device has to be retracted with care or will be damaged.You can not exceed 50 pounds pressure on the plunger.The simplest method is to reract while still in vehicle, it takes 15 minutes to properly retract the plunger.By pulling up on the tensioner by hand with about 18 pounds of force --50 will be exerted at the plunger.When fully retracted insert pin to hold in reracted position.Next check to make sure that cam wedges are holding and no sprocket are trying to move,when satisfied remove one of the rollers at the bottom on the side where you left hand would be standing in front.Pull off belt.Replacement belt will have referance marksone line will go to crank sprocket face up others will line up with other sprocket marks.Reinstall roller followed by tensioner then pull pin you have holding tenioner retracted.Remove wedges.Reinstall covers fans belts.Do not be intimitaded by this replacement.Everything is very easy to get to.Be sure cams are locked and that damage is not done to tensioner and it is straight forward.
