Default Cummins will not fire

Hello everyone, I have a 2003 Cummins that will not fire up. It worked fine one day, then I tried starting it a few days later and it'll turnover but not fire up.. I get no codes on the dash when I turn the ignition key 3 times. I can hear the lift pump spinning in the tank and the grid heaters are working because the intake is warm to the touch. Any ideas?? If I were to crack open one of the hard lines to the fuel injector and the crank the engine, will the fuel dribble out or spray out??

DO NOT open one of those high pressure fuel lines and try to crank it. Your engine compartmentwill promptly be coated in fuel.

Could be a few things....

ECM could have committed suicide. Very possible. May explain why no codes are being thrown.

Injection pump may have crapped out. Ahhhhhh, maybe. Wouldn't think it was the lift pump, as it would fire up just not real well.

Cam or crank sensor could be toast. Again, quite possible. No timing, no fire.

Or, maybe just a fuse.
