hi, there won't be power to the other side of the solenoid ,

the red/lt blue wire comes from the ignition switch but passes through the neutral safety switch first .

if the truck starts when you jump from the hot side of the solenoid and to the terminal on the solenoid that the red/lt blue wires attaches to ,then you need to trace that wire to the neutral safety switch and also, see if you have power on that same color wire at the ignition switch ,there should be power at the ignition switch on this wire only when the key is in the crank position .

if there is then the neutral safety switch may be bad ,

also, try to start it in neutral ..jazzmaster ..
