I just had one of my crank sensors replaced and car started and ran just fine. Had oil changed and two rear tires put on the same day, different places. The next morning I started my car with the automatic car start and it started. When it turned off I tried to restart it and nothing. I went out to manually start it and all there was was a click. There is juice from the battery because the radio, lights and etc all come on. I put jumper cabels on and it started right up. Ran ok the rest of the day but noticed at night when it was really cold that the dash read "Battery not charging" but it was running and we made it home. Figured it was just due to the cold because other lights were stuck on like the ABS system and someothers. The next morning same thing 1 click and nothing. Bought a new battery nothing, but every once in awhile it will just start up, but still reads battery not charging and if I shut it off and turn back on then nothing. Any ideas??
