Put key in ignition and have power for dash etc but when try to start nothing happens.No crank at all. Starting system fault shows up,as well as advanced trac, brake system and oil change warning. The latter codes randomly showed up one day when driving. The starting system fault appeared when just sitting , not running, while trying to charge old battery. The battery said full and I tried starting it and fault appeared. Both factory keys/ fob do the same. I have a new battery ( did it on old battery too) I have tried disconnecting/ reconnecting battery. Have checked the fuses interior and in power distribution box as well as the ignition relay. Have made sure the connection in the inside fuse box is good. I have run out of things to check. Could it be pcm relay?
