Answer
Terri,
It sounds like you've covered some major areas already.  Check the fuel pump and pressure to be sure it getting to the injectors.  Check your mass air sensor for any damage.  Also check your charging system and ignition coil.  If the alternator is not providing the proper power to the ignition coil or the coil itself is not functioning properly, you'll get no spark.  Inspect the fuses on the positive battery cable and the relays in the box under the hood. One final thing I can think of to check is the car's computer.  Some ECUs in Mitsubishis in the early 90s have some major problems with damaged capacitors.  But that doesn't mean later Mitsus could have a problem as well.  Pull it and check for any visible damage to the circuit board.
Good luck!
