not sure what blocked them, all i know is fuel wouldnt flow through 2 of them til i replaced those, than they all flowed fine. I am goin to go out and dump a thing of anti gel in the tanks, take a heat gun to the lines and see where i get from there...

Certainly sounds like a possible gelling issue to me. Drain the fuel filter, fill it with a good fuel conditioner (trying to recall which one Dave and others suggest) and see if it will fire. That will also put some through the IP and injector lines. If you can't get it in somewhere to warm up, you may want to disconnect the supply line at the lift pump, and back at the tank, and see if you can blow it through....sometimes it can be a real fight to get badly gelled fuel cleared out of long lines in cold weather.

If you put the additive in before it gels, all antigells work wonders.
911 does a fine job in the tank, but if you have wax blocking a line or the filter, it has no way to get there.
A couple hours in a warm shop is the easiest way to get the lines cleared.
Out in the cold country, most road services bring a generator and one of those turbo heater out with a tarp cut about 4 feet tall with wood stays they can wrap around your truck to block off the wind under the truck.
Once the air is blocked off, the heater blowing hot air under the truck will thaw the paraffin blocking the fuel lines so fuel can flow through them.
As soon as you have flow, the 911 will take care of the rest of the wax.
