Several steps are involved, though, in getting the fuel to the injectors. In contrast, with the HPCR system, the engine or power train control module (ECM or PCM) governs the rail pressure, fuel metering, injection timing and engine speed control. In a PLN system, an inline injection pump handles the following functions: delivery of a pressurized and metered quantity of fuel to the injectors once for each power stroke control of fuel injection timing governor control of engine speeds and fuel delivery quantity related to the engine operating conditions. Also, modern common-rail diesel injectors can fire two or three times per engine cycle, doubling the wear on the injector compared to diesels of the past-hence the need for more conscientious maintenance. Many older diesel injection systems only create about half the fuel pressure modern engines do, and older injectors send the fuel through much larger passages. Starting with the basics, a high-pressure common rail fuel injection system (HPCR) used in the GM and Dodge heavy-duty pickups since the early 2000s is quite different from the previously used Pump- Line- Nozzle (PLN) systems (like those found on a P-Pumped Cummins for example, but not like those found on HPOP equipped Power Strokes). Thus, their technicians know their stuff and are a great resource for repairs and performance upgrades. This well-known company not only services a large number of hard-working trucks but also builds championship-winning drag racers and sled pullers.
Instead, we’ll show in the accompanying photos some of the basic steps and tools used to evaluate common rail injectors at an experienced shop, Scheid Diesel.

Note that space doesn’t permit covering every possible fault code on an OBD scanner, or an extensive list of SAE diagnostic procedures, as that would require a massive manual. Then we’ll focus on a few common concerns encountered on common rails. It evaluates the pump’s rpm and has a common rail attached with sensors, so the pulse width can be adjusted to three or four fuel set points.īefore getting into those details, we should first clarify how a common rail differs from other types of fuel injection. Scheid’s test cell evaluates the flow accuracy of a CP3 pump and common rail injectors.
Be it common rail Cummins problems, fuel control actuator issues, 6.7 low fuel rail pressure codes, or the like, the following should help you with common rail diesel troubleshooting. Many of these problems, however, stem from things unrelated to the design of a common rail system, which common rail owners should be aware if they want to minimize expensive repairs.

If the injectors are replaced prior to making sure all fuel lines, fuel rails, and injectors are free of metal and other debris, your replacement injectors may fail prematurely.Although common rails are an improvement from prior types of fuel systems, they’re not without their issues. Prior to installing your replacement injectors on engine, identifying the root cause of the failure is very important. High pressure common rail injectors are a critical part of your diesel engine’s operation and are also vulnerable to foreighn debris, poor fuel quality, or water in fuel.
