You can probably use an advanced scanner - but you'd have to bring it to a shop

try unpluging the one you think is bad if the noise goes away you found it

You can use a mulitimeter and use the ohm setting, just put one prong on each side and the injector should be between 12-20 ohms. This will tell you if it is working , but doesn't tell you if it is clogged. I had a clogged injector for about a year before It was found and replaced. Would throw out PO300 all the time. I replaced just about everything until it was finally found by accident.

Actron Model CP7819 Fuel Injector & Harness Tester

I got mine a few yrs ago, helped find 2 dead injectors when I was doing the 3800 swap. Cheap price, and more inportantly, it works. With injector testing, you can trigger an injector once or multiple times (3 clicks)
