Need help figuring out what is wrong with my 92 ...

there are so many things that would cause you situation.  Since you had just recently added gasoline, my first thought is that the fuel you bought is the cause.  It could have water in it and when you stopped, the water settled to the bottom. when you started again the water was drawn into the injectors.  The fuel may have had some debris which settled and clogged the pump input strainer.  The fuel pump could have failed. One of several sensors could have failed which would cause the engine to not run.  I would pull the trouble codes to determine where to start.
