Angry odd issue with car not starting

so i have this really odd problem with a car i am working on i have a 2000 outback with a manual transmission i bought the car with a bad motor i drove the car 20 miles with the original motor started and moved are you with me....

so i replaced the motor with a complete engine from a 2003 forester x at first i left the forester intake on it cause i was being lazy and left it on ..... so i go to start the car, just turns for about 10 seconds then stops (more on this later)....

i figgured it was just the intake as i just was being lasy i knew i had to have the orignal put it on and try to start the car expecting it to fire right up guess what NOPE cranks and cranks ... somehow my buddy convinced me to swap out the ecu with one i had laying around which comes from a 2000 legacy gt (automatic) and it fires right up

odd didn't think to much about it and move on with everything and go for a test drive i soon find out that the car is not drivable with the automatic ecu and i believed that using the forester intake caused me to damage the original ecu which leads to the no start condition so today i go and buy a replacement and expect the car to start .... AND GUESS WHAT IT DOESN'T
odd ball stuff .... so i put the auto ecu back in starts no problem

i really dont think that i have 2 broken manual ecus both allow the car to crank for about 10 seconds then i stops like theirs resistance i tried to turn the motor by hand and it feels like something is binding up in there so im thinking that its fuel in the cylinders i really don't understand how the automatic computer fires the car right up every time but the original one does not seems quite odd but there has to be a reason can someone please give me some ideas ?


SUMMERY :
2000 legacy outback Manual
engine from 2003 forester x Manual and the original intake manifold

runs with 2000 legacy gt ecu
does not run with the correct ecu (orig and a replacement)

starter stops turning after 10 seconds or so of cranking time, seems to be resistance ... hydro locking

crank gear and cam sprockets are from the forester engine i just slapped the legacy intake on the forester long block upon looking up the timing gears it seems that they are all interchangeable between

2000 leg gt At
2000 outback mt
2003 forester x mt

Yeah the manual Legacy gets the different crank sprocket that may be your issue. Sounds like it.



Forester/Impreza only use the AT type sprocket from 99-04.

Thats why it started with the automatic ecu, those use the same crank sprocket as Forester.
