Have a problem with starting. Truck had an alarm system that I took off. Reconnected the wires back to factory. Installed a new battery-starter cable. Checked and had no radio and no power windows. Found two relays missing and one fuse under the hood missing. Installed new. Tried again and have all accessories but will do nothing when turning key to start. With key on I can jump across solenoid by starter and it will start. Once started it will not allow me to shift out of park. If I shut truck off and turn key to on position I can shift out of park and into neutral and jump across solenoid and it runs. Once I shift back into park it kills the truck and we start all over again. I've traced wires and fuses and can't find anything.
Ideas would be greatly appreciated

 

It appears that power through fuse 21 is missing to the start relay.
This power supply runs through the ignition switch in start position and DTR switch in park and neutral to the start relay.
Fuse 6 supplies the shift interlock circuit and the GEM so could affect the power window operation as well..
Both are on the dash power panel.
Anything else is hard to tell about, at this point.
Good luck.

 

Yeah I searched fuses and can't seem to find anything. It's just probably something simple but I'm not finding it. I've checked and rechecked wires that I took out and it's just not working. But thanks for the help

 

If the fuses are in and good, then you need to follow the circuits with a voltmeter to see where they get lost.
The shift release is a solenoid that is powered through the brake pedal switch.
The pedal has to be pushed before the power is allowed to the release.
Good luck.
