check the resistance across the terminals, assuming their high-impedance should probobly be somewhere in the 12-14ohm range, if you have a manual it should specify or perhaps you can find the info online.
take a 9v batt, run wires to each of the injector terminals... it should "click" as it opens. hold it open (keep the battery connected), and spray carb cleaner through it, make sure you getting a fairly decent spray out of them... as far as i know thats about as much as you can do at home.~Nate
