Do you have issues with your 2003 5.9L Cummins injectors?

Indications of a diesel injectors issue:

First, does your truck exhibit one or more of these signs or symptoms? If that’s the case, it could be a diesel injector issue.

• Light colored exhaust coming from the exhaust pipe. If there is any fuel injectors sticking closed, then your truck’s diesel engine won’t get adequate amounts of diesel. This diesel shortage will cause the truck’s engine to starve for fuel and will result in white smoke coming from the exhaust.
• Dark colored smoke coming out of the exhaust. If you’ve got any fuel injectors that are sticking open, the truck’s engine will get an excessive amount of fuel, resulting in excessive dark colored smoke coming out of the muffler.
• Truck running poorly or not at all. If your injectors aren’t operating properly, the truck’s engine won’t be receiving the right rate of diesel. When this happens, your engine may not operate at all, and it definitely wouldn’t run properly.

What is the cause of diesel injector issues in 2003 5.9L Cummins Engines?

Every once in awhile diesel injectors go bad, most often subsequent to bad fuel . When this occurs, the vehicle will possibly experience poor power, excessive white colored or dark smoke coming out of the exhaust pipe, and there are times the truck will not operate at all. Failure to repair bad injectors can easily result in severe damage to the diesel engine, so it is necessary to fix failing diesel injectors as soon as possible.

These are typical reasons for diesel injectors to fail:

• Bad diesel or contaminants in fuel. When your fuel is bad or is contaminated, it may clog up your vehicle’s diesel fuel injectors and result in them not working properly. When this happens the diesel injectors can stick open, stick closed, or the tip of the injector could break off. In the best case, this could cause your vehicle’s diesel engine to operate improperly. In the worst scenario, it can cause the engine to not operate whatsoever or perhaps even trigger extensive damage to you truck’s engine.
