I replaced the brain ,pcm,from a 99 durango same motor and it runs like it wants to die and still have no bus and guages not working so can I drive like this and how do I fix it,what's my next step now that truck starts and runs

 

Need to figure out the no bus error.

 

That's for sure but I don't know what to do to locate that problem,I thought a new pcm would fix it but it didnt,didn't, have a pcm from same year and motor on its way from a junkyard hopelefuly that will do it ?

 

Maybe pcm needs reflashing to your truck.Alarm systems must be in sync with that vehicle its programmed to..
