We have a 97 subaru outback limited 2.5 We just rebuilt the engine and Bought new parts for it too. We replaced the battery and all the gaskets. The engine does receive fuel and generates spark. We also checked the injectors to make sure they were generating fuel also, everything seems to be working fine, the timing is dead on and at top dead center. What else could make the car not start?

You could carry out a cylinder compression test, or check the ignition timing.

You sure its not on the exhaust stroke? If okay check the fuel pressure if its within specs and also for injection pulses

You'll need a compression gauge. Screw it into the spark plug holes and crank the engine with your foot on full throttle. Check all cylinders and compare

How do we do that if its a split motor? The only way to do that is if we take out the engine, there is no room to get to the spark plugs

You could try to see if the engine will run briefly with easy start spray. Have someone spray a small amount into the intake while cranking. Don't do this for too long. If it runs briefly you can kind of assume all is ok mechanically and focus on fuel or ignition.
