have you confirmed that the ecu and wiring is actually connected and undamaged? Sounds wierd that it wont even crank over. Also to reset the ecu did you pull the ecu back up fuse to reset it?

Well i was posting that because i know with hondas you usually just pull a fuse to reset the ecu but i know with the evo you can also just unplug the ecu as well since the plug is in the engine bay. But technically disconnecting the battery should work.
Are you using the original marching key? There's a tumbler sense wire that is coded to the ECU that is coded to the key chip in turn.
Can you read the ECU with something like a tactrix cable? The misfire codes sometimes come from other things, like running lean could cause a cylinder 2 misfire but it's unrelated to cylinder two, it just happens to be cylinder two that misfires first
Other thing is check the throttle position sensor, and IAT is intake air temp I think, which could be intake related.

Update:
Yes, original key. We got the car running by jumping the starter (I know, not the best idea). We connected power to the spade portion on the starter and it fired right up beautifully and the codes have all gone away.
Today we will test if were actually getting power signal to the starter spade or not. I don't think we are and that's where our problem lies. Any idea why that would be? Could it be that the starter is "weak" and will only jump-start? or do we have a wiring issue?
All the CEL lights are now off. The only thing on now says "AWD system service required" and "ASC system service required".

There are a total of 12 placed on the car's chasis (behind door panel, under the dashboard)
If a single one is shot u will not be able to fire up the car as the immobiliser needs all signals coming from them before u could fire it up
I am assuming it is an MR (with auto) otherwise you would have tried a push start...
Check simple stuff first. Try starting in neutral (not park). Maybe it is the starter interrupt switch.

Hey guys so heres an update after a few more hours with test lights.
The car starts up and runs perfectly(aside from the service awd note) if we jump power to the spade on the starter.
SOOOOOO in my head, i next went to the starter spade portion of the harness, (small black clip that slides onto the spade) and did a key turn, and go figure, no power is to that plug in the harness. Ive examined the clip, wire, etc. and cant find any damage.
Thats my problem, now to figure out how to fix.
Anyone have any wiring diagrams for the starter area and how they should be powered with Key off, and key in start position.
Thanks in advance.
