When you drive your diesel vehicle often, you get to know it well. The engine\u2019s feel, the performance you can expect, and the efficiency of a good diesel engine become familiar. Sometimes, though, things start to change. You might have to fill your tank more often than you used to, or your truck might not give you the same response when you push the pedal.<\/span><\/p>\n

There can be many explanations for a change in your diesel vehicle\u2019s performance, but one of the most common causes is a clogged <\/span>fuel injector<\/span>. Knowing <\/span>how to tell if fuel injectors are clogged<\/span> can save you a lot of aggravation, time, and potentially money if you address the issue before it gets worse.<\/span><\/p>\n

Symptoms of Clogged Fuel Injectors<\/strong><\/h2>\n

Once you know <\/span>how to tell if fuel injectors are clogged<\/span>, it can be easy to notice the symptoms.<\/span><\/p>\n

Reduced Engine Performance<\/strong><\/h3>\n

When there is a clog in the injectors, your pistons don\u2019t get the right amount of fuel needed at a given moment. That makes your engine work harder. The RPMs will be lower or inconsistent, and you won\u2019t get the same feel from your vehicle.<\/span><\/p>\n

Worse Fuel Economy<\/strong><\/h3>\n

The harder your engine has to work, the worse your fuel economy will get. If you are filling up more frequently, a clogged injector could be the issue.<\/span><\/p>\n

Trouble Starting<\/strong><\/h3>\n

Another potential sign of clogged injectors is difficulty starting your vehicle. The restricted fuel flow can even prevent your truck from starting at all.<\/span><\/p>\n

Poor Emissions<\/strong><\/h3>\n

The fuel injection issues will carry over to your car or truck\u2019s emissions, which will get noticeably worse as the problem persists.<\/span><\/p>\n

How to Test Your Fuel Injectors<\/strong><\/h2>\n

You can test your <\/span>fuel injectors<\/span> to determine if they are clogged. The methods of doing this vary in difficulty and the equipment you will need. Whenever working on your engine, make sure you wear safety gear like eye protection and gloves. Also, make sure the engine is not hot when conducting any tests that involve touching components of your engine.<\/span><\/p>\n

Listen to Your Injectors<\/strong><\/h3>\n

You can test your <\/span>fuel injectors<\/span> by turning on your engine, placing the end of a long screwdriver or metal rod against an injector, and then putting your ear to the far end. If you hear clicking traveling up through the rod, then the injector is working.<\/span><\/p>\n

Use a Test Light<\/strong><\/h3>\n

You can get an inexpensive ohm meter or test light that will enable you to touch each injector to see if it is functioning.<\/span><\/p>\n

Temperature Check<\/strong><\/h3>\n

You can carefully check each cylinder by doing a rough temperature check. Start the cold engine, and then flick a little water on each cylinder to see if it burns off. A cold cylinder should become apparent as the functioning cylinders warm up.<\/span><\/p>\n

What to Do with a Clogged Fuel Injector<\/strong><\/h2>\n

If you do indeed have a clogged fuel injector, you have a few options. You can try to clean your injectors yourself with a diesel fuel injection cleaner. However, if the injectors are highly clogged, this might not do the trick. Injection cleaners tend to be better for preventing clogging than for cleaning out current blockages.<\/span><\/p>\n

The primary treatment for a clogged <\/span>fuel injector<\/span> is to remove it, take it apart, and clean it. This can be tricky, though. If parts get damaged or not put together correctly, the injector will not function. Your best bet is likely to take it to a skilled technician to inspect and clean the problem injector.<\/span><\/p>\n

The best way to address clogged injectors is to prevent them from occurring. Regularly add diesel fuel injection cleaner when you fill your tank, do an occasional thorough fuel injection cleaning, and make sure you get the best <\/span>fuel injectors<\/span> you can from Dieselogic.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
