check the rail pressure, if its not making 1400psi of rail pressure it will not start

that would be where i would start since you were working on the injectors, also a noid light test will tell you if the ficm is trying to fire the injectors or not

No problem man, I didn't take any offense to it at all. I am at the end of my limited knowledge is all. That's why I said good luck.
