Default 2005 2.5rs no spark

I posted this thread on the Impreza forums but there was no response so Iím going to try on this one. I have a 2005 impreza 2.5 rs the engine blew I bought an 04 engine put stock intake manifold I drilled and tapped the egr valve whole new spark plugs, new oil, drained gas put new gas, crank and cam gears, changed ecu, distributer, changed all the sbf connectors, tried immobilizer there is none, changed the Maf sensor, Checked timing, new battery the car cranks but no spark. Does anyone have any idea what it could be ?

Connect a regular light bulb instead of the coil and see if it blinks during the crank.
If it does than coil is bad. If not check your wiring, ecu and crankshaft sensor.

If you haven't done or perhaps know of this already: check the injectors by placing a screw driver against it and press your ear on the handle and hear for clicking when you turn on the ignition. That will at least mean it's spurting fuel or at least trying to.

if you have verified power at the coil then the last things to check is the fuel regulator and possibly air.
