1986 F250 cranks but wont fire
Hi. I know this is an F150 page but I've seen some stuff on 250's etc and I am beyond stumped. I have a 1986 F250 with a carbeurated 460. A couple months back I made a sudden stop at a light and it died on me. Now all it does is turn over but won't fire. Checked ignition control, coil, cap, rotor, and wires. Can't for the life of me figure out what is going on. Any help would be greatly appreciated. Thanks!

Check to see if fuel is going to the carburetor. Theres a fuel line going into the carb, disconnect it and run it into a folgers can, and then crank it over and see if fuel pours out of the line. If no fuel comes out, then the problem is that. If the fuel lines run to close to the block, you will get vapor lock, which means fuel boils in the lines, resulting in no gas getting to the carburetor.
