Ive searched all over and havent found much yet so heres my issue.

Randomly shut the truck off one day, and now it doesnt crank. It has a new battery, starter, and starter relay. If you jump the relay it starts up everytime. All cable cable ends seem to be ok. Is the ignition switch the problem? If so what is the best way to test it.

 

Sounds more like a neutral safety switch problem.
Either at the clutch peddle or on the side of the transmission.

 

Sounds like you get to become a better friend with your multimeter. As subford already said, neutral safety, then check to see if you have voltage at your key, then coming out. Just start tracing with the meter till you find whats bad. This an auto or a manual?

EDIT: So your neutral switch will be your clutch pedal assembly with a manual.

 

It is a 5 speed( forgot to mention that)
