Changed the battery in my vehicle tried to crank it would not start. The next day it cranked every time. Went out the next morning to warm up the truck by the time I went out to get in it had shut off and has not cranked since. We replaced the cam sensor and the crank sensor but still not getting spark. It turns over but it is not catching.

Check fuse #10 in the power distribution center (PDC) located under the hood, left (drivers) side.
If that fuse is okay, try a new automatic shutdown relay in that same PDC or swap a non important relay of the same type into that spot and try again.
The front blower motor relay looks the same and is right next to that ASD relay, see the diagram below.

That did not work. Really need help. We tried disconnecting the battery did not work. We did the lock and unlock in case it was the security shutdown. Nope.

Do you have voltage to all the red wires at them ignition coils, with the key on run and start?
If yes, then make sure all the PCM fuses are okay, they are 18 and 34 in the junction block (left kick panel) and 16, 18 and 22 in the power distribution center located under the hood, drivers side.

If so, you may want to retrieve the engine trouble codes cause a crankshaft and/or camshaft position sensor may be preventing spark.
