How You Can Spot Faulty Diesel Fuel Injectors

New lb7 injector

Your diesel fuel injectors are central to your truck’s performance, so it’s important to spot when they are not working well. With the right tools, like a Duramax injector removal tool, and the right knowledge, you can spot and address any injection issues that come up. If you notice any of the following signs, it may be time to replace your injector set completely.

  • Strange Noises: Any odd banging, clanging, or grinding sounds may trace back to your fuel injection system. If fuel is not getting delivered properly, the entire performance of your car can suffer. There also may be other structural damage or loose fuel injectors, so watch out for these.
  • Fuel Odor: If you smell fuel while you are driving or idling your car, there is likely a problem with your injection system. Check your injectors for leaks, as loose fuel may be causing this smell. If you can’t pinpoint the answer yourself, take the car to a professional.
  • Excess Exhaust: Especially if the exhaust is an unusual color, your injectors could be to blame. Whether fuel is not being injected properly or leaking, your combustion chamber could be running on almost nothing, causing the car to produce a dark or white-colored smoke.
  • Trouble Starting: If your engine is puttering or delaying at start, it’s time to get your engine checked. Again, if fuel injection is not happening when or as it should, the entire system is missing the kick it needs. A well calibrated system should help your engine start on command.
  • Check Engine Light: Is your check engine light on but you can’t seem to find the issue? A diesel professional might point to your injectors. A faulty system is a big red flag for your engine, so be sure to address this quickly.

When you spot the above signs, it’s time to address the problem as soon as possible. Whether you own your own Duramax injector removal tool or need to take it in to a professional, the effort is what counts. Fine tuning or replacing your injectors will get you back on the road in no time.
