Anyways, I have read a post on here where someone had a similar problem.
https://www.2carpros.com/questions/1996-dodge-dakota-truck-wont-start
I followed that and checked wires, connectors, unplugged coil and the like. I did the bulb test and only got the bulb to turn off from the fuse terminals after unplugging the black connector on the PCM, also the light will dim if I unplugged the right side grey one as well. Does this mean my PCM is bad?
A little background on the problem,
After fixing the trailer lights that were wired weird I had no break lights and after tracing wires and looking in the OEM shop manual I found the break switch led to the multipurpose switch on the turn signal lever.
I moved those wires about and the brake lights started working again, I marked it up to living on a rural dirt road and the thing wiggled loose or something like that.
I put everything back together and drove to the gas station about 5 miles, coming home truck died on me, it fired back up and got me home. The next day I drove it about 500 feet and died again, fuel pump wasn't working, at this point I did not notice the blown ASD fuse. The fuel pump would not pump, and the electric fan would stay on with key on, I unplugged the ASD relay, and the pump would work, but engine wasn't getting spark or fuel pressure was bad.
I then dug into the book and internet and began to double check everything and noticed the fuse blown. There was a 60amp in where it should have been a 30 amp for the ASD.
Without that fuse in I cannot get the computer to give me a code I did for a short time get a code after soldiering the fuse back together, for an air intake sensor (PO113) but then the fuse blew and lost connection.
I did the light bulb test and got the light to go off as said above and that was the only way for me to get it to turn off or dim with the other plug unplugged. I tried wiggling wires, unplugged coil messing with fuel injector wires and well I can't find the o2 wires. I hooked up a wire chaser beeper to the fuse terminals and have beeping sound over at the PCM plug.
I don't want to spend 200 on a new PCM if it's not the problem so any help will be much appreciated. I'm not a mechanic by trade but I can read and watch videos and figure most things out. Like my pop always said "if there's a will, there's a way".
Thanks!
