Anyone else have an idea?

Any other ideas of what might cause this?

The oxygen sensors would cause the car not to start ?

I can connect and see the led lights up green. Is there a difference in what tells the 05/06 ecu when to fire injectors and spark, versus the 04 type ecu? Thanks for the input

I diasable the immobilizer and you can see the rpms during cranking. I put in a type r ecu and it fires up and stalls after few seconds, but I think that has more to do with my throttle body. I just want to know for sure if I have a bad ecu or something out of place.

Motor swap a k20a2 into a 98 civic. End use ktuner ecu, no spark or fuel pulse while cranking. Any ideas would be greatly appreciated.
