Question about Vehicle Parts & Accessories
Test them with an ohm meter, they should all have near the same resistance across the two terminals,
and the best way to clean them is by filling your gas tank with a good grade fuel and adding seafoam to the tank, you can get it at any auto parts store and most hardware stores

You can check to see if the injector is cycling by touching it with a long screwdriver then put your ear on the handle you should be able to hear clicks ( motor must be running) I use sea foam in my gas to keep fuel system clean

Put a long screwdriver directly on the
injector while the car is running. Hold the handle up to your ear. You
should be able to hear a rhythmic clicking sound. If you do, your injector is
good. Hearing a clunk-clunk type noise means you have found your problem. Hearing silence or unusual clicking
patterns means either the injector, wires or plunger may be bad or sticking.
You will either have to clean or replace them.

Many a times you get black smoke from exhaust due to faulty injectors.Check fuel injectors. Leaking injectors create an overly rich air/fuel mixture and cause black smoke. Take the valve cover off and look at the exhaust part of the injector, when it is running. Each time the injector fires, you should see oil exhausting from it. If you see oil coming out, then the injector is good. When replacing a bad injector, take the glow plug out and crank the engine to get any oil out of the cylinder.----------------- This should help.Thank you.
