The company we bought it from programs PCM before sending it to you.

When we try and start truck with new PCM it won't crank theft light will flash a 2 and 3 and from googling that it says key does not match PCM. So just trying to figure out if this sounds right or is it possible company did not program new PCM. It will sometimes flash a 1 and 6 to not sure what that one is. Is it common to have to get keys reprogrammed even if PCM is programmed for that vin

you are probably talking about a 1600 code which means the key doesn't match. you'll have to get this reprogrammed at a dealer. I really don't know how someone can sell a pcm already programmed when they don't have the vin. If it is it's just a general one. If you change a pcm it HAS to be reprogrammed for the vin including keys/keyfobs

So dealer says there is a short somewhere that its not the pcm. So any ideas on what it might be? Truck will not start on its own you can spray it with ether and it will start right up and run just won't switch gears if you drive it only if you manually switch it and then it's only 1st and 2nd

did they check the fuel pressure? it may not be turning the fule pump on and was the inertia switch checked to see if it is kicked on. why was the pcm replaced to begin with? there are porbably 200 wires running to the pcm so asking where the short is is kindo fnil at athis point. the circuits will have to be traced down to see whichone it is. i would start with the fuel circuit or see is there are any bent pins on the pcm where it was connected first. did the dealer reflash it or what exactly did they do?
