no bus

[fairplay]

hey I got a 2000 dodge 2500 pickup and for the passed year my truck has been shutting down on the dash it shows (no bus an the engine an gas light is lit) I've had it tested on a computer I have done a complete tune up changed out the crankshaft, and camshft on the truck I also changed out sensor relay for the fuel and I just found that my blower relay was burned out
I was just woundering if the burned out relay for the blower might be the cause of the truck shutting down
Any advise would help

Are you driving when it shuts down?

I would consider looking around the pcm on the passengers side fender for any loose connections as well as near the fuse box. A blown relay may be a side effect of an issue with the fuse box.

The PCM connector as stated above is a chronic issue with that year. It's said that the connection with the bolt comes loose and causes this problem.

Are the three ground straps there that go from the back of the heads to the firewall and one over to the Pcm? If not get some.
