When you say the truck didn't want to turn over, do you mean the key is dead, nothing happens when you turn it to start? Or, the engine spins normally when you turn to start, but the engine fails to start?

Nothing it just a clicking from seliniod

I've got the battery unplugged now because of a constant clicking coming form the fuse box inside my truck I pulled the relay slot making the clicking sound and with the relay out its still remains clicking


A clicking solenoid is an indication it is bad, there is not proper voltage to start the vehicle, or the solenoid is not properly grounded to the fender well, usually. As for the clicking from the fuse box, you stated you removed the relay and it is still clicking? Don't believe the relay can remain clicking if not receiving power from the battery.
