Exclamation NEED HELP EJ25 SWAP WONT START :mad:

So I just completed my ej25 swap into my Impreza one it was phase II to phase II so everything plugged in right where it should have but ofcourse with my luck I can’t get it to start and for the life of me I can’t figure out why. I mean I primed the damn motor before I even tried to start it. Now I can say that it did burp a few times and actually did try to start and turn over once but that’s all I got. Also I could hear the exhaust puffing like it wanted to run. I definitely know it’s getting fuel and I checked my plug and wires(which were newly installed) and nothing. All good. I just can’t think of why it would puff and burp like it wants to start but can’t. Could it be cause I used the ej22 starter? I have it grounded on all points like how it was in my legacy outback. I never put the rad or ac condenser in because I wanted to get it started before I put everything back and wasted two gallons of fluid and $25 bucks worth of refrigerant.
PLEASE ANY INFORMATION YOU MAY HAVE COULD HELP!!
Thank you!
:edit: so I got the car to start but now the trans won’t engage I’m thinking it’s because I need to bleed my brakes because they go right to the floor and I never hear that click I used to hear when going to move so again any help will help me. Thanks.

Check the valve timing and make sure it's good. Do you have access to a scan tool to check sensor readings?

When you say check valve timing Iím not sure what that means. Lol like take the heads off or valve covers? I know itís prolly not that but like I said Iím not sure what you mean. I was thinking of getting a timing light and seeing if I was off cause I know even the smallest amount off on timing could keep the motor from starting.

You need to make sure the crank sprocket and the cam sprockets on the original engine and the new engine have the same pick-up points. If not, then all the sprockets from the old engine need to be installed on the new engine so the ECU gets the correct inputs.

I'm guessing what you've got in the car now doesn't match the old engine, so the ECU is seeing signals from the crank and cam position sensors that don't make sense, which is why it isn't starting. You probably have no spark, because the ECU isn't firing the coil(s).

So should I swap ECUs? I didnít know about the sprockets. Iíll check those tm. Thanks.

Swapped ECUs and the car started right up but now Iím having trans issues. It wonít engage and I assuming itís becuase of all the Grammy fluidni lost because I did not put the cooler lines on the hard lines before starting it. Oh well.

OK......deep breath........

Is this an AT or MT?

Based on "cooler lines", I will guess AT.

If you have AT cooler lines just hanging in space, you WILL lose ATF. Thus the trans won't engage due to low fluid level (also likely a huge puddle of fluid under the car).

Give us more info, but I think my post gives a direction......

PS, your post sorta sounds like....."I did an oil change, but left the filter off, why is the low oil pressure light on?".

Yes, harsh.
Think about it, does it make sense now? Or did you leave info out?!?!

I have an Outback Legacy with a 2.0 that I just put a T belt in, which is setup perfectly. I've checked it several times to make sure. I've had a buddy who owns his own shop come look and he says it's perfect.

The T belt broke on the freeway, towed it home and changed the belt. NO START situation.
Here's the fun part,
We know the belt is right and it has fuel getting to the engine: 80psi in and out of the filter with great flow.
We have spark, I just put in a new coil because I wanted to take any doubt out of that system. New coil, new plugs, good spark.
Compression is #1, 200 psi #2, 150 psi #3, 200 psi #4, 200 psi.

New ecu, new coil, new plugs, new crank sensor (just because I was trying to figure this out)
Fuel, spark, compression, NO START! I and my buddy have checked everything we can think of and I am out of ideas. It's been sitting her for three weeks and I am supposed to be going to California and am stuck here with a no start Outback that's making me go completely buggy!

I could use a hand if anyone has any ideas? I'll try anything!

What crank timing mark did you use? Some use the one on the front of the crank gear which is incorrect. You need to use the one stamped into the disc on the back of the gear.

Since it was highway running when the belt broke and you have a cylinder that is 50PSI low, that could also have a bit to do with no start.
