You need fuel, spark and compression for it to run.
Did you check the fuel pressure? Can you hear the fuel pump run?
Did you check for spark? Check at the spark plug while cranking.
Did you check for compression?
Did you have your replacement ECM programmed to your VIN number?

I have done all but program the ECM to my VIN wasn't sure you had to.
