ive got a 2002 chevy 6.6l deisel, im having problems getting it to start, the engine turns over just wont fire, the only way it will start is if i spray some brake cleaner down the intake, once it is running it runs great until you shut it off, i just took it to florida for a trip and had noproblems with it starting down there, on the way home when the weather was a bit colder had the same problem, ive checked the glow plugs and they are all fine, any suggestions

Do you have any mods on the truck "programmer, ect...."

Also do you have any current or stored codes?
