ok i have a 99 5,9 auto 2wd durango with the stock securty system.so im getting the no bus code and i dont here the fuel pump every one says i need a new pcm or crank sensor so i have put two of each in and it still randomly turns off or will drive fine then not start when ever it feels like it. so im lost and about to put it in the field and shoot the sh*t out of it. any help would be vary much appreciated befor i pull out the ak...

 

o and there is no spark to

 

is there power to the coil?

is there fuel pressure at the rail?

the no bus code is a problem, but there is a sensor in the truck which can take down the whole bus if it goes bad, im sure master tech will post up with it when he sees this (im not sure which one it is atm)

 

there is no fuel presher at the rail and im only saying theres no spark because if i fit it with starting fluid or put gas in the intake it still wont even try to start

 

some one said that no bus means the the cluster is not talking with ecm is that true

 

When I bought my D it did that and it was the pcm.

 

well i put two new ones in with no luck

 

yes a no bus codes means that there is a communication problem between the PCM and the cluster (ecm is a ford term, and if you use that term going to a dodge tech will cause him to screw you)

check the ASD relay, that is one of the constants between the pump and coil, and who knows what other sensors, i really hope Master tech chimes in with the sensor that i mentioned above.

 

sorry i have a ford to lol but ya i checked the relay and all the fuses all good but ill have to check into the cluster i had a heater core put in about a year ago so the had to pull the dash out and thats about whem this all started i would say but would that really make the thing shut down

 

anything is possible, one bad ground is all it needs to really screw up the electrical paths
