Check fuses and fusable links.

Are there any fusible links inside the cab, or a main fuse. I dont have any power coming in to the fuse Box in the cab

ok i feel like a dumba** i found a wire tucked down beside my batt. i hooked it up and i have power now but no crank and no fuel pump,the security light is flashing and showing all kinds of faults on the desplay screen. do you have to reset the computer after having all that out or is there some thing else wrong

You probably still have a wire not hooked up or a loose connection.

Check the ground under the cab on the right side.

Check all three plugs for the cab harness under the master cylinder they have to be connected all the way

Try unplugging the small round plug on the pass side and touching it to the battery. It should spin the motor over, then plug it back in should crank with the key then. My brothers truck and mine have done that after having the batteries out for a while. Not sure why but it will reset whatever is locking it out, for us anyway.

Thanks for all the help I finally got it there was a power wire off on the drivers side. I guess thats what I get for working on it with two hours sleep I two days.
