Motor is cranking and not starting

I have fuel to the front of the rail, the spark is mad crazy, so I think my injectors are not opening?
I cleaned ground at end of rail and reinstalled, popped 1 time, then nothing.
Jumping it from another car, did nothing, so tomorrow Im going to swap ECU's and MAF...

ECU was from a running car, but MAF, I am not sure....

opinions, thoughts, questions?

thanks

ps: Im also going to switch cam, and crank plugs...would things like ECU, MAF, and Crank Sensor, make injectors not open?
