Big A$$ electrical problem
well truck is in the shop and can't seem to figure out what the problem is. The truck isn't throwing any codes to the computer they're hooking it up to. The whole warning light cluster is on, don't have a speedometer or the rpm gauge, and transmission is just giving me all sorts of trouble. Shop just put in a $900 p.c.m. in and none of the lights have gone away and i don't know where go next? I figure maybe there is a bad connection to the batteries through the cables or something, another thought was maybe something is getting grounded out through the fuse box, or could be a possible short somewhere in the sensor on the rear end. Any Ideas?

mine was doin the same just about the same thing and it turned out to be a broken battery terminal. also check grounds n clean everything up. have your alternator checked, have your batteries checked, if none of that turns up anything, try the crank position sensor. check the small stuff first.

There is a ground behind the kick panel that likes to corrode and cause all kinds of havoc with the cluster....also pulling the harness on the back of the cluster and clean the terminals as they can get some corrosion on them. Check out the CPS as it tells the PCM the engine is running and turns everything else on....sometimes the wiring on it can develop cracks as well so check that whole thing out.
