Ive been haveing a problem starting my 2415 for quite a while....first, when the key is turned on it makes the clidking sound while the plugs wrm up...when the clicking stopps i turn the key further to the right and sometimes it starts and others it just clcks at which time i wiggle the key clickig it each time and eventually it catches and start. thts one problem...tonight I turned the key and the clicking indicting the plugs were warming up, started but it never stopped....it keeps on clicking and I cant figure out if the plugs are not heating or what....if I continue the key to the right nothing happens
