Hey guys! I have an automatic 06 convertable base trim (I think...interior looks really cheap) that wont try to start. I got it last summer, it initially had intermittent trouble starting. Replaced the battery, fixed the issue for a bit. Problem came back, cleaned the ground clamp and the issue was fixed until I parked the car for winter. Finally had some good weather so I tried to start car - problems back. No start, no crank. Fan races. Charged and tested battery, its at 12.97 volts. I installed a new ground cable and rcm - still no crank. Going to get some e-torx sockets later so I can do the engine block ground mod and eliminate bad ground as a possibility. The jumper ground under the car is pretty rusty, could a bad ground cause these issues? If not, any idea what else it could be?
