Installed new timing belt on 1992 Subaru Legacy. Set all 3 pulleys to TDC as per Subaru Manual. Spark check ok. Took off hose from fuel filter and cranked over with plenty of gas coming out. Car is hard starting and when it does start, it only runs for 2 or 3 seconds, backfires, floods and dies. Car has not been used for 3 months. This car has an electric fuel pump. Is too much gas being delivered? Is there also a way to check or bring up trouble codes on this car in case it is a component problem, or a fuel jet problem?
I had the same symptoms. I had to count the correct number of teeth from the crankshaft pulley to the cam pulley marks.It is a different number of teeth to each pulley.It turns out that I was off by one or two teeth on one cam.

It is important that you turn the engine in the correct direction. To achieve TDC firing stroke remove spark plugs insert a plasic straw into the number one spark plug hole and proceed to turn the engine over observe the straw keep turn ing the motor until the straw travels upward when it stops moving up stop turning, you will know you are at tdc by looking at the timing marks down on the crankshaft pulley the notch on the pulley should line up exactly to the number zero on the timing plate at the front lower part of the motor very close to the crankshaft pulley turn the motor over again and again until you line up the notch on pulley with the number zero you may need to clean the numbers off on the timing plate or front cover.
the haynes manual makes it sound worse than it is !!!!, once you get all the extra,s out of the way ( radiator etc) its not too bad ... the are marks on all pulleys and on the heads,line everything up before you start and realign as you go ( things will move a bit as you work), also a good time to change camshaft seals ( if needed ) ..when resetting the cambelt adjuster ,slowly compress it in a vise insert a split pin pop rivet etc , into the hole so to hold it in its compressed postion reinstall it on engine , make sure all marks are aligned and only then remove pin to release tensioner..turn engine by hand at least twice making sure all is good before starting engine.
Valve Timing sounds off to me (belt driven to valves) You are assuming the timing marks on the heads AND your engine drive pulley are OK, right? Heads could be 180deg out which is easy to fix by taking off the belt at the heads and manually rotating the pulley once and retesting.
Pull a plugwire, shove a rope of twisted tinfoil into it and see if it sparks to block. If you get fire, then my very strong guess is that the spark and Gas/Air compression cycle aren't happening at the same time and the valves are 180deg out.
your timeing marks are on the block rite abouve the cams on either side and on the block in the middle but line the center mark on the teeth there is a mark not the arrow the arrow is where tdc is the mark is on teeth good luck.
The water pump is run by the timing belt.Involves the draining the antifreeze,removing the radiator/condensor fan motors,harmonic balancer,alt./ac./p.s. belts, timing covers and timing belt.Along with a new pump,a new timing belt should installed.Timing marks are critical and it should be repairer by a garage.Should take about 1 to 2 hours or so to do if everything comes apart easy.Also there is no cap or rotor,only a coil pak.Hope this gives you a better idea.
Check for water in spark plug tubes, ign. wire connector ends & coil pack for corrosion.
All marks go up, the crankshaft sprocket has an arrow that you don't use! if you position the crank sprocket where the key way is down you'll notice that the sprockect has a timing mark at the top of one of the sensor pickup teeth, use that. Here is a rough home made pic. I hope this pic made it, no conformation that it did.
