I have a 1997 F-250 Diesel Truck that will not start. It started for a couple of minutes then stopped and I can not restart.. . battery seems good... engines turns but won't catch... have electrical connection to heater block to keep warm.. have snow plow on the front... need help to start... have put diesel "heat in tank" but no help. The red wait light does not come on when I try to start it. It used to come on and then shut off and then I could start but now no wait light.. Help?

If it was cold enough, your fuel may have gelled. Get it somewhere warm (garage) and let it thaw.

Hope that helps.
