it sounds crazy no one belives me but pull your fuel rail you and a freind hold the injectors into the fuel rail and put a couple of rags under them and a 3rd freind starts the car you shold see a good spary come out of the injectors its a shade tree way to check injector firing(ther is a injector resitor that gos bad on some cars i think a 92 has one or your computer is not firing the injectors) if you have a test light you can also tap into the ground side of the injector use a safty pin and hold test light to the pin dont jam the test light int the injector harnes and hook the test lights other end up to the ground side of the batery start the car you will see the light fliker it could also be an a/f problem let me know if you have injector fire
