no start and now codes
i was ready to leave work today, turned the key to run position and none of my gauges in the dash came up. tried to start it and it wouldnt. i went under the hood took both battery cables loose and checked my XZT connections. reconnected the batt and gauges came up and truck started. i now have codes: p0106 map sensor high
p0107 map sensor low
p0643 sensor 1 high
what are these and what do they mean?
p0107 map sensor low
p0643 sensor 1 high

P0106 Manifold Absolute Pressure Sensor Performance / Rationality
P0107 Manifold Absolute Pressure Sensor Low
P0643 Sensor Reference Voltage 1 Circuit High
Could be just a glitch, could have been the MAP sensor connection. Does the truck run normal now, I assume no Check Engine Light is on.
BTW there is a code list in Tech FAQs above:

the truck runs normal now but, i got the same three codes this morning again. it was very wet on my road yesterday. could these codes and the no start be caused by some water in the MAP sensor plugs? or dose this sound more like something gone wrong in my XZT harness(it has the bypass plug in it)?

When you say you got the same three codes again does that mean that they were cleared? Or does this mean you got a CEL again this morning and the same three codes are there? I would remove the XZT wiring harness completely and make sure there are no bent/broken pins in the connectors. Put it back to stock and see if the codes go away. Better if you can have them cleared with scanner/downloader if possible.
