first. thanks for this being availible. and if its not in the correct area let me know.

2005 3/4ton 4x4 automatic
seeing the abuse an miss n parts. cry n in the beer, drink n the beer and now go n forward. after putting battery ends and batterys in it. have no plug in communication with the plug. if this had the function by useing the switch on/off, third time on to see codes in odometer window it does not work either. holding the odometer trip button and switch on does show c codes but are no help to the no start or communication problems. (using the key) in the on position does light the dash functions and they do cycle, does make the heater fan work. ((BUT NO GAUGE MOVEMENT)) then on to start position it does crank the engine over. no power to fuel relay circuit. have jumped transfer for fuel to inj. pump (10psi) but notta on start or smoke. in looking threw the general wireing diagram and get n into the column this truck does not have the (module sentry key immobilizer) or coded key. how ever it did have the radio ripped from the dash (cut wires). does the radio have any sort of thief no start powers.? if there are any rays of light you folks could respond with (things to check, things to try, or where to look it would be appreciated bunches.. thank you gw

 

The truck is down so this is the right section. I work on the old dinosaurs so I'm not much help, but I edited the title so folks would have a clearer idea of what your trouble is.
