How I clean my fuel injectors.
This is how I clean my injectors for a ZC/D16A1. May not work for everyone.
I went to the junkyard and cut off the injector plug along with a couple inches if wire. I solder the two wires to the wires on a 2-AA battery holder from radio shack.Cover the solder joints with liquid electrical tape coating. Then, take the screen out of a bad or spare injector. Stick a thin red straw from a can of carb cleaner down into the screen.Now fill in around the top if the screen with some JB Weld, and let dry for a couple days to fill in around the top of the screen and straw. After dry, take a very sharp utility or exacto knife and cut off the botom of the screen, exposing the open end of the straw. Remove the screen from the injector you want to clean and stick the straw/screen combo you made into the injector. Plug the 2-AA holder with batteries into the injector to open it up. Hook the open end of the straw into a can of carb cleaner. Aim the injector nozzle into a GLASS jar. Spray to clean out the injector good. After you feel it's clean enough, spray some kind of lube like WD 40 thru, so the carb cleaner doesn't sit and destroy the internal seals inside. Replace all your o rings, and let dry then reinstall. THIS MAY NOT WORK FOR ALL INJECTORS.Did wonders for my JDM ZC that had been sitting forever. If you leave the carb cleaner in the injector for a while without rinsing it out with WD 40, it will leak fuel Don't ask me how I know.
Hope this helps somebody.

How do you burn up injectors? I haven't done one yet. I only energize them with 3 volts for a few seconds per spray. Isn't the actuaton voltage like 5 volts? I'll let you know when any of the 12've done fail. So far 2 &1/2 years good.

fuel injectors are designed to operate for a few milliseconds at a time they are turned on and off very rapidly by the ECU. If you give an injector power and ground for to long it is posible to burn out the solenoid winding in the injector when this happens the injector will no longer open.
