I'm currently searching through google and the forum for help. Posting because I'm confused as to whether its my PCM or ECM also clueless. 

 

Last night I was driving and I parked and shut off my truck. I did switch my tune to one I got from here but used previously without any problems. A few minutes later I started my truck just fine as always and about a second later it shut off. 

 

ODO flashes "no bus" / no wait to start light / overhead says "ccd" / gauges don't work / airdog won't turn on , cranks strong but gets NO fuel at ALL / connected scan tool but says it can't connect / also phone seems like phone can't connect to quad adrenaline

 

some extra info about my truck-- 150hp inj / 650 trans / head studs / 

First thing I would do would be check all grounds. Make sure they’re clean and tight. Test each battery individually. Make sure battery cables are clean and corrosion free. Have you done the W-T ground mod? 

Doing that right now and I have not done the W-T mod(I don't know what that is) maybe the previous owner did, I'll look it up thank you

Had the smallest of hunches that it was related to the quadzilla. Took it off and the fuse it blew and started right back up

 I believe @Mopar1973Man had a vaguely similar issue, IIRC it was a ground for the quad.

 Even though she's running again I would suggest checking and cleaning as many grounds as you can. Very important on these trucks and as they age things need "freshened up" a bit.

Mine the bolt for the ground came loose.
