This morning I stopped and got a coke at the store and my truck had ran fine. When I jumped in it to go I turned the key and nothing. My gas gauge was jolting back and forth and the only light that came on was my service engine soon light. Well I popped the hood and wiggled some wires on the battery and still nothing. I turned it back off and then on again, then all the interior lights and gauge lights came on like normal, but I didn't hear the fuel pump. Tried to start it and it fired up but died instantly. Tried it again and it fired right up. Drove to work and when I pulled in the driveway I turned on my foglights and everything started acting up again. Turned it off then started it up again and everything works as it should now. WTF? Could it be a bad battery? I have heard of batteries causing all kind of ruckess. Any suggestions? Thanks
