so the other day i go to start my truck and as soon as i turn the key to on, the starter engages and tries starting the truck without me turning the key to start. thought it was the starter. replaced starter didnt change anything. anyone have an idea as to wear to look for the problem now?? im thinking the ignition tumbler or something. any help would be helpful. thanks guys
