Bad fuel injector or as was my case on my 87, corroded and broken wires going to the fuel injector on that cylinder. Try switching the fuel injectors from cylindes 2 and 3. If 2 still won't fire its probably the wiring. If 3 won't fire its the injector itself. There is a sharp bend in the fuel injector wiring close to the injector plug that can cause the wires to get brittle and break.

the truck is only firing on 3 cylinders 1,3,4 nothing on 2 it has spark but no fuel. EFI does that have seperate injectors for each cylinder?
