Hi, I own a 1996 F250 with the 7.3 engine, since I bought the truck about a year ago I have been having a lot of cold start issues. When I first bought the truck most of the glow plugs were bad, so I replaced all of those along with wiring harness for them etc. A week ago I got caught in a snow storm in the big horns, and what do you know, truck doesn't start up. After a while, I would turn the key and even with both batteries having jumpers on them along with the block heater having been plugged in for about an hour and a half nothing started. Soon, the key wouldn't crank anything over. A key that was helping bridged two wrenches to bipass the starter, that worked for a while and soon didn't anymore. We couldn't get a crank or a click from turning the key, but when the key was in the "on" possition a long series of clicks was coming from my fuse box in the engine compartment. Eventually we pull started the truck, and got home without turning the engine off, as soon as we did however it didn't crank at all. Any tips for the startup? both cold and not? Would it be the glow plug and starter relays?
