1985 CUCCV k5 blazer no start

[Dozer5478]

I have a 6.2 K5 military blazer, its a no start, we have replaced the Fuel pump, glow plugs, glow plug solenoid. we have either it every time when cold it starts with either once warm, will start back up :bang. I cycle the plugs two or three times allowing the light to turn off. still a no start. The problem started before the cold winter. I was told the fuel was old. I ran it out and put new in. ANY IDEAS

Are you sure that the glow plugs are any good?

You can check them with a test light (the clamp end of the test light to battery positive), and the sharp end to the glow plug. If it lights, the plug is good.
Check to see if the glow plug solenoid is actually energizing the plugs (use a test light, clamp end on battery negative, sharp end on glow plugs)

Also check for fuel leaks (rubber lines). Make sure there's no air getting into the system.
