My 1993 Geo tracker fuel systen is not working, the injector is not spraying. now it is sprayin on the inside of the carborator and filling the carborator up.. how do i fix this problem//

There is no CARB on this car.
that must be the throttle body engine, TBI EFI.
1 injector engine not the 4 MPI engine.
G16a is TBI G1b is TBI and both sold day 1 , new.
its is supposed to spray, but you forgot to say when.
just key on over and over not running, (not spray is correct)
it sprays cranking and running,, that be its job1.

lets say it sprays key one.
That means:
1: injector leaks.
2: injector - o-rings are bad. (cracked)
3: ECU injector drivers shorted (bad ECU)
you can look at the inject on this car, air pipe off TBI horn.
see if the seals leak or injector tip leaks ?
if the injector actually leaks.
unplug the injector connector (4pin plug)
leak now.
yes, injector is bad or just o-rings
no, the ECU is bad. (common on this car)
i can even tell you which transistors are bad.... etc.....ask.

both engines covered here.
