I have an 86 f250 diesel non turbo 6.9, it was running fine yesterday, and this morning she started, ran for a minute, revved up and died, the fuel pump is clicking when the key is turned and both tanks are full... does anyone have any ideas how to fix this? Any help is greatly appreciated, thanks

 

On top of the fuel filter boss is a shrader valve(like a tire valve). Poke this valve and see if you have fuel coming out.

If you do, loosen one of the injectors and crank it, and see if fuel oozes out around the loosened injector line.
