97 Dakota 5.2 V8. Had wrong PCM in it. All dash lights on and no gauges work. Back light and turn signals work though. I have two different PCMs but none are the correct one. However, when I put the other PCM in, all the gauges work but runs like terrible. Yes I did check the crankshaft position sensor and camshaft sensor. Bought both new and installed. So today, I bought a new PCM from AutoZone for truck $333.83 and hoping this will eliminate the NO BUS and have the gauges working because I am tired of guessing how much gas I have in my tank. I will be picking it up in 7-10 days and letting you all know how it goes.
