Default 03 wrx 2.2l stroker UTEC no spark?!?

A little background:
03 wrx 2.0 block bored .020 over, manley coated stroker pistons, eagle rods, sti crank, sti cams, stock valvetrain, hta68 turbo, modded stock inj, ngk plugs, tuned by dan at mach v

I changed my clutch due to the previous one slipping, got the car back together and it didnt want to start. ended up replacing starter and battery cables and grounds, and now I have it cranking. I have fuel and compression, however I am getting no spark. If I remove the utec and hook the stock ecu back up I get spark as the car will sputter and try to kick on but it will not stay running.
After hooking up the stock ecu I threw a p0102 MAF high input code.

Basically, when I hook my utec up I have no spark. This is a new condition I have had it over a year with no issues whatsoever.

Anyone have any ideas? I have checked the position of the switches on the utec itself, they are fine. The red led is on bright so it IS getting power atleast.

Saw this same issue about a month ago. Utec is bad. Have the car tuned on stock ecu and dump the pos utec.

Is there any way I can confirm thats the problem? its just odd to me that it would die randomly during a clutch job when it was working perfect beforehand. I really hope this isnt the problem but i swear ive checked everything else and I was just about ready to admit that it was the issue myself.. ughh.

Also the car will not actually run with just the stock ecu, but I can hear the difference when cranking that I am indeed getting spark with it and not the utec. im thinkin maybe its just the modded stock inj keeping it from running on the stock ecu though. ANY INPUT IS APPRECIATED

do you still have the same start up problem in map zero, if so double check your harnesses to see if they are seated well before giving up on the utec. It could be bad

I double checked the harnesses, everything is connected properly. It seems like the spark problem goes away on map zero as the car will sputter, however the car still will not start and run.

It's probably fouled out the plugs at this point
