Car won't start just put a new battery in.
So I parked my car one night woke up and it wouldn't start. Everything worked but the dome lights. Replaced the battery cause the old one was only reading 11.5 v , so now all accessories work , I put the fob in the gauges light up but nothing move ie the gas gauge etc. I hit the start button to start it and everything shuts off? I really dnt know what to do next please help! Thanks
