i know that this is not the thing that this board deals with but not having any luck anywhere else - have 6.9/7.3 diesels and the glow plugs dont seem to run long enough to get hot enough to start -they have the late style controller and new plugs - but what tells the controlller how long to heat the plugs?? my 458 t/p 70 mach 1 never has any of these problems
