New Holland TN55 Won't Start after changing Filter.

[myboyblue85]

I have a New Holland TN55 that won't start up. Two days ago it was running then shut off and wouldn't start back up (it would crank but not catch). Battery, starter all that is good.
I looked at the fuel filter and it had sludge on it so I changed it, but still wouldn't start. I bled the line until fuel got to the fuel filter and filled filter, then I bled all three lines until fuel came out but still won't work. It will crank but not start.
I'm guessing it must be something small but I' not sure. Please let me know

Check the fuel shutoff solenoid on the injector pump. Stand next to pump, turn key on and off. You should hear the solenoid click. If not, check the wire going to it and the fuse that controls it.
