The car didn't want to turn off yesterday so I changed the batteries of the fob key thinking it was that because in the dash it came out that they were low and even so the car did not want to turn off.The previous owner removed the steering lock control and the fuse so I don't think it's that. Now sometimes the car turns on and sometimes it doesn't. I have a direct killswitch to the bcm that disables the ignition button, tomorrow I will check and try to remove it to see if it is. At the moment all the fuses are fine, all the lights works and I can lock and unlock the car with the key. Any other idea what it could be?
