i have a 1994 f250 with a 7.3 idi swapped from a 1990 f250 the glow plugs used to make kind of a clicking noise before and now there is no noise and also the voltage does not go up and down like it used to. What would be a cause of this? Also my temp guage is pegged on hot and never used to do that. Any help is appreciated!
