To clarify Doug's post, you don't actually remove the injectors. There are two plates that hold two injectors each snug into the intake. Fuel lines are attached to the injectors individually. Those lines need to remain attached but will probably be quite brittle. Be very careful as you remove the two phillip's head bolts (sometimes allen bolts) that hold those retaining plates in place, and pull the injectors out of the intake. Get a couple of jars or a deep tray (a small oil pan works well) and rest the injectors inside.
Now remove the large rubber bellows, as doug mentioned, that goes from the air filter box to the intake. Once you do that you'll see a round disk/plate in the middle of the air filter box. It is connected to the fuel delivery system by a 10mm bolt I think. That bolt head should be visible. Using a pair of pliers you should be able to grab that bolt and lift the plate up. This simulates what happens when the engine is drawing lots of air, ie under full throttle. When the plate rises a plunger in the fuel distirbutor (the adjacent section where all the fuel lines connect to the air filter box area) drops, allowing fuel to flow to the injectors. The fuel pump provides over 40lbs of pressure on the lines so when the air flow plate is up there is plenty of pressure trying to push fuel out of the injectors.
you've done this next step before. You need to jumper the fuel pump so that it runs constantly. Doug indicated which connections to make. if you can't figure those numbers out simply jumper the connection closest to the engine bay to the connection closest to the fender when standing on the passenger side of the car. This will pressurize the fuel system. You do not need to turn the key on to make this work.
Once you have everything in place, move the the driver's side of the car and pull up on that air flow plate with pliers. This will send fuel to the injectors. Make sure there are no sparks or open flames in the area. Fuel should start to spray in the pan/jars. You are looking for a misty, cone-shaped spray pattern. If fuel is "streaming" or shooting out in straight lines, then you have a clogged injector. If nothing is coming out then you have a fully clogged injector. Lifting and lowering the plate can start to free somethings up after a bit. Try that first. I have used very small pliers to pull the small valve in the end of the injector out as well with success. If you can not get the fuel to spray properly you will probably have to remove the injectors from the fuel lines and can try a few things then, like soaking them in carb cleaner or something. You may still find a shop that cleans injectors by hitting them with some un-godly amount of pressure. Good luck with that one.
If something in this description is overly confusing let me know and I'll see what I can do to help. Good luck.
