Question about 1993 Chevrolet C1500
Yes very common problems with the "spider" fuel injection unit.
Remove the top of the intake manifold to access the FI "spider unit"
The injectors can be replaced separately. Also sometimes it's the pressure regulator that's bad, and leaking so check for that too.you can check the injector spray pattern if you are careful doing it.(disable the coil, have lots of rags and a friend crank the motor while you check the pattern of each injector) (hint - if you are really cheap you can actually "clean" the end of the injector with a small screwdriver , try to roll the ball around to remove varnish, then recheck the spray pattern.
