No Bus - No Start

No Bus - No Start
I have the following codes along with No Bus in the dash. Under this condition the 2000 Ram SLT will not start. I have the entire front of the engine off as I'm fixing a timing cover gasket leak but know the ECM threw the following codes...
P0202
P0132
P0207
Anyone with any insight?

Also, (MoparFanatic21) lets talk PCM's, This is one I picked up at a local yard from the same make/model Ram as the original PCM took a dump within 14 days of an as-is purchase, replaced it worked for a while. One day while driving around the neighborhood it sprung a critical coolant leak, as coolant drained we limped home. Replaced water pump, attempted to start it, No-Bus & No-start, coolant still leaking. Found the coolant leak to be the timing chain cover, so I've began that repair. Could, and I mean is there any way when the engine lost compression based on the timing chain gasket failure it killed the PCM? Am I dealing with two separate matters?

So (HeyYou) I know the o2 sensors could use a changing, but cars/trucks have driven for years on bad o2 sensors and not caused a situation like this. In your experience has o2 sensors caused No Bus with a failure to start?

The dodge system is kinda strange...... it's basically a small computer network in your truck. PCM talks to CTM (central timer module, essentially a network switch) which talks to the cluster, etc. If one of your five volt sensors is failing, the PCM gets confused, and stops talking. To anything. Hence, no bus.
Supposedly, you can find the failing sensor by unplugging them one at a time, until the cluster starts working again. Of course, with some sensors unplugged, it's likely the engine won't run anyway.
Timing cover gasket has nothing to do with PCM, nor would it be responsible for low compression. You have several problems you are fighting.
