My car 2000 accord has been sitting in a parking lot while I went to vacation and when I came back battery was drained. I put a new one and as soon as I connected the battery car's alarm started along with the car cranking without a key in the ignition. It keeps doing it and doesnt turn on even when I try and put the key in and turn it. I think someone messed around trying to start it without the key and it somehow got stuck. I changed the starter, the ignition, spark plugs, checked the fuses. . .I am running out of ideas. . .Please help me I love that car I want it on the road.
Thanks!
Andrea
