when run codes get "NO COMM"
I put in a new battery and now I'm getting all kinds of elec problems. Getting all the codes "reduced engine power" "Low fuel" the fuel gage reads empty the water temp pegs to the hot side, no power windows, no auto settings on the power seats, no radio, trunk won't open, etc. the car will start and runs ok. When I run a code check everything comes up NO COMM. Anybody got any ideas how to fix. I have unplug the battery and waited 10 min no help.
