you can take the pcm off and take it to your dealer.

 

could...

 

unplug the wiring harness, unscrew the computer from the truck. if your looking at the truck its mounted on the passenger side.

a haynes manuel (from any auto parts store) would really come in handy for you. Its a must for dodge owners.

The thing is i never got a key fob when i got the truck...so i didn't know i had one....

 

NO BUS means your trucks CCD network has failed. It could be a PCM but other things can cause the failure too. Any computer connected to the CCD network that shorts will kill it. Any shorted CCD wiring or any shorted 5 volt sensor will also bring the network down.

Before replacing any more parts I would unplug the following engine sensors one at a time. Crank sensor, distributor sync, MAP, TPS. If the NO BUS disappears you found your problem.
My money is on crank sensor.

 

thanks ill try them

 

cant find the Crank sensor on my truck and it wasn't an of the other things you told me.

 

Found it...but didn't fix my problem
