my 93 7.3 is not acting the same way, when I turn the key to the on position the glow plugs are not cycling as long as they use too, they are new plugs too, it still starts but requires more crankin, also there are many clicks afterwards and there is an extra wire run to a switch under the dash from it, but not hooked up any more, I am thinking I should replace the relay module what you all think? Oh and it has new glow plugs less then 1000 miles ago
