Hard Starting
Hey guys,
I've got a 2000 f250 with the 7.3 and, even in 50* weather, it takes at least a minute of cranking to start. I've heard about watching the electrical meter to the left of the speedometer and I noticed that there is no change to it from when I turn the ignition on. Isn't it supposed to be a little low then pop back to normal when the relay turns off? I'm getting a new fuel filter and air filter soon but I suspect that it is the relay. Also, it blows a lot of white smoke when cranking and for a few minutes until it gets warmed up. Thanks!

Sure sounds like the Glow Plug Relay (GPR) or glow plugs (GP's) or both. Take a screwdriver and jump the two large posts on the GPR for about a minute with the key on, but not started (KOEO). If it starts right up, you have to replace the GPR...to test the GP's you need a multimeter to check their resistance (ohms). That white smoke you are getting is unburned fuel...give away the the GP's/GPR aren't doing their job. How long are you leaving the key in the on position before trying to start your truck?
Here is a thread with lots of cold, hard start issues...

I'm betting the GPR is toast...
