There are two main reasons that diesel fuel injectors wind up failing, both of which have to do with damage to the injectors. Ford F250 owners can read on to find out about a few mechanical reasons that explain why diesel fuel injectors fail and a few warning signs it’s time to have them replaced.
Mechanical Reasons for Failure
The most common reasons for diesel fuel injector failure are worn injector ball seats, leaky crossfeed tubes, and blown internal high-pressure seals. Cracked nozzles and injector bodies and incorrect nozzle needle clearance can also contribute to premature failure.
Indications of Imminent Failure
If a diesel engine requires increased cranking time to get the engine started, it’s likely time to look into replacing those worn fuel injectors. This isn’t the only indicator that it’s time to replace ford f250 fuel injectors, though. Low common-rail pressure codes constitute a second, easily identifiable issue that indicates the need for replacement.
Prevention of Damage
There are a few things truck owners can do to prevent premature wear and fuel injector failure. The quality of fuel and cleanliness of the overall system can have a dramatic impact on how quickly fuel injectors show sign of wear, so it’s always smart to purchase fuel from reliable sources and to change fuel filters as needed according to manufacturer specifications. Overly aggressive tuning can increase rail-pressure, so truck owners should never remove pressure-limiting devices from their systems.
Other Signs of Imminent Failure
Other signs that a truck’s fuel injectors need to be replaced include high balance rates, loss of cylinder compression, rust or debris clogging the injector nozzle, excessive exhaust gas temperature, incorrect injection rates, and incorrect parts. While many of these issues can be avoided through providing the vehicle with adequate maintenance, all fuel injectors will eventually need to be replaced.
Tips for Purchasing New Fuel Injectors
Be sure to purchase replacement parts from a reliable automotive parts supplier and resist the temptation to purchase less-expensive, remanufactured fuel injectors, as these often fail quickly, leaving truck owners with unnecessary bills. Once the new injectors have been installed, be sure to use only high-quality fuel and provide the fuel system with adequate maintenance per factory specifications to prevent premature failure.
