I suggest that you take it to an auto parts place. If you are not able to do so, then if I were you, I would call a tow truck to get it there for you, and then see if a friend can pick you up and bring you there to deal with checks for having your car fixed or whatever.
There’re a number of reasons that would explain why your truck will not start. The carburetor or fuel injectors could be clogged, which means that the fuel is unable to get to the engine. You should probably have it towed and checked out by your mechanic.
