lately the stater on my pickup has been busting my balls. the starter itself is brandy new (changed because of this problem) and sometimes or most of the time the starter will stay ingaged, even with the key off. the way i get it to stop doing this is if i cycle the ignition switch from the start position to the off postion. now i suspect the ignition swich at the end of the colum is sticking. anyone ever experience this? and how was it fixed?
