Ej208 in 2004 WRX not firing up

[Griefenhagen]

Looking for suggestions on why my car wont fire after engine swap.

ej205 threw a rod, ordered a used engine and they sent a ej208 that had already been converted to single turbo.

I took everyones advice and swapped the crank and cam gears as well as their sensors.

I upgraded to a vf48, sti intercooler, ID1050's, deutchwerks fuel pump, flex fuel kit.

I put in a new timing belt and water pump, basically replaced everything that could be.

I used the entire intake assembly from my ej205, I dont know if that matters.

My tuner gave me a bvase tune with all of these changes accounted for but it won't fire. It turns over and sounds fine. I believe it is getting fuel - not sure about spark

Am going to try bypassing the flexfuel kit and change the tune eliminating it. after that I really am not sure what to do. Maybe try swapping the coil packs from my old engine since I know they worked.

Does anyone have any thoughts or what I should try if the flexfuel bypass doesn't do anything?

Any help is much appreciated, thanks. I have my dyno tune on july 8th and I really want to make it, otherwise I won't have my car back until August! ugh

Timing?

It should be good, but may have to take it back apart to check. Had everything perfectly aligned before releasing the tensioner.

Turn the key to the on position without trying to start it. Do you hear the fuel pump cycling?

Yes it's getting fuel to the rails. 48 psi just with the key turned to on. Tore the timing cover off, timing is perfect. Compression tested cylinder 1 and 3 had between 150-160 on both. It got dark and I wasn't able to get the other 2 cylinders yet. I tested for spark all 4 coil packs are working. The spark plugs were brand new, the 2 on the driver side were pretty sooty, and the 2 on the passenger side were way cleaner. I'm not sure what this means, if it's not getting enough gas to the passenger side, too much? Injectors not working correctly? I'm confused. Everything we tested worked as it should as far as I can tell

I'd go back and check all your grounds. Check for contamination on the terminals. Check the wires and see how pliable they are. If they are stiff you could have corrosion inside the wire causing issues. Check your fuses and if they all look good then maybe replace one at a time to if anything changes. Sometimes fuses can be bad but hard to visibly tell. If you repined anything in the harness or the ECU, make sure they are in the correct position. Make sure the green test plug is disconnected as well.

Does it throw any codes? Maybe a bad sensor causing it not to fire up.

Did you ever get it figured out? I'm trying yo do the same thing to my car. Kinda worried now
