"No bus" light on dash means what exactly?

Asked by Mar 26, 2016 at 02:41 PM about the 2000 Dodge Ram 1500 4 Dr SLT 4WD Extended Cab SB

Question type: Maintenance & Repair

My truck will turn over but won't start, I caint hear
the fuel pump prime, all idiot lights are on but
gauges won't work, after about 10 seconds with
the key on the second click the millage box starts
blinking then it says no bus. I've checked all fuses
and such they seem to look fine, the coil and
distributer cap are all on tight and there isn't any
fuel pressure on my fuel rail. What's wrong with it?

Check all of the PCM connectors, make sure they are tight and plugged together properly, check main power box connectors, ignition switch connections etc. doing these checks could save you a trip to the shop. This is a common message on Dodges, so common there are some videos on you tube, you might want to check them out.
