Engine won't start

I bought a '81 300D and it would start easily through the fall, when it started to get cold (25-32 deg F) it was still starting. I went out and tried to start it when the temp had dropped into the 20's and I have not been able to start it since (even now that it is summer time). I have checked the glow plugs, I replaced the priming pump and fuel filter. I have loosened the fuel lines at the injectors and I am not getting much fuel squirting out when I crank the engine.

1985 300TD Fuse 14 blowing

Fuse #14 keeps blowing. Here are the electrical issues I've noticed:

1. The car will only start in neutral.
2. The glow plug buzzer does not go on (but the glow plug light works).
3. After the buzzer stops working the AC blows hot only.

Fuse #14 certainly could impact the AC because according to the fuse diagram it controls "control unit/water pump/heating water valve for climate control system.....". But what about the neutral safety switch and the glow plug buzzer?

My diesel starts great idles on all 5 no miss but when you start going down the road she misses intermittently at lower rpm quits at mid and high range rpm until she is up to temperature then she's fine she doesn't smoke and she has power up the kazoo any idea's? I have run 2 can of diesel purge set the valves no change. Bad injector maybe?

Thanks
