How many fuel injectors for a 1995 S10 22L and where are they located?

yo man i just replaced the injectors in mine pretty easy job you need 4 of them and get some vasoline. dont try to push them in they seat way easier if you put something against them and tap it with a hammer. make sure they are lined up right with the little plate that holds them on.thats pretty much it probobly want to replace the fuel filter too under the driver door insde the frame. hope this helps
