1999 Cirrus 2.4L, No Start

I have a 1999 Cirrus with a 2.4L. It cranks over but will not start. I have no fuel pressure, no spark and no injectors. The instrument cluster says NO BUS.
Just wondering if anybody has run into this before.
I checked the cam and crank position sensors and they are good. I was hearing maybe PCM or wiring.
One other question is, if i replace the PCM do i need to get it programmed at the Dodge Dealer???
Thanks
Brett
