Injector test?

Well I finally got a PC1 to go into my 84. The set of brown-top injectors I have have been sitting in a box for easily 4-5 years. Is there any way to test them out or prep them aside from sending them off to cruzinperformance? A set of new o-rings is obvious, but I am hesitant to just throw them in and trust them.

Well... If you just want to check if they work or not, get yourself a 6-volt flashlight battery and very briefly energize the injector with it (keeping in mind the correct polarity). It'll click if it's functioning. I don't know if it's bad for the injector or not, but you can take a can of that sensor safe cleaner and hook the can up to the inlet of the injector (be creative and make an adapter). Then, with the nozzle depressed, briefly energize the injector to see if it's clogged or not.

This will not tell you if it's flowing properly or not; just whether it's clogged or not. I have done this and it didn't seem to affect the operation of the injector, but I'm not going to say that it can't mess it up because I don't know.
