When you try and start it, what is it doing? Nothing? solinoid click, then nothing? turning over but not firing? Be discriptive and details.
Also describe wha tyear and model truck and what if any mods have been done

 

can't really understand what your problems are... need to rewrite post

 

it is a 97 4x4 2500 with a 5-speed as far as mods just 100 plate 3kgsk 35/40hx turbo. once i put the battery and cleaned all the connection it start and runs but the tack, a/c, alternater, curise still dont work. when it would not start it just act like it had no fuel at all i cracked the first line on the injecter pump shot a lot of starting fuild and and fired up and keep running fine got it turned off then start it right back up and drove about 300 miles but nothing worked and the radio would cut off and on but i didnt turn it off the whole way also it comes and goes it will work a little at different times

Start at all fuse's [ in cab & under hood ] & fusible links at diver's side battery .

 

You say you cleaned the PCM connections.
My experience has been that if you disconnect the PCM the odds are high that some connections may become bad.

 

my 95 recently developed a glitch in the ignition where you put the key. when you start it sometimes you have to turn it back just alittle bit to make some electrical items work. Affected items are, cig lighter plug ins, radio, turn signals and the hazards. It did take alittle investigating to figure out why these items stopped working and yours might be a simple thing like this.
