is the glow plug relay going out a common problem on the Ford 7.3L power stroke? I now have a 02 Ford F 350, 8,4000 miles which I believe the relay is fried , before this truck I had a 2000 which every fall as it got colder I had to replace along with the glow plugs, Is one brand of relay more reliable then another for example ford vs. napa?
