DIESEL truck FUEL INJECTION SERVICE
DIESEL INJECTOR SERVICES
At Cummins Automotive & Diesel Service, we offer expert diesel injection services. Call to inquire about diesel fuel injection system diagnostics and assessments for your truck’s fuel injectors.
SCHEDULE SERVICEThe goal of our diesel fuel injector service is to restore, or maintain, your diesel engine’s power output according to manufacturer specifications in order to maintain or improve both fuel economy and emissions reduction. We will remove, inspect, and clean the injectors; or repair, rebuild, or replace them, whichever is appropriate. We will also service the common rail if tests reveal doing so will be a benefit to your engine’s efficiency.

DIESEL FUEL INJECTION SERVICES
Cummins Automotive & Diesel Service has been servicing diesel injection systems on diesel trucks for more than 10 years. We are held in high regard throughout the Northwest for superb fuel injection service.
The goal and aim of our diesel fuel injection services for Ford, Chevy, GMC, and RAM trucks, are to maintain and/or to restore the fuel injection system to its manufacturer specified standards in order to equip the injection system with the capability of operating in sync with the truck’s full complement of powertrain and electronic components to give the truck the possibility of maintaining the emissions reduction efficiency and the fuel efficiency that the manufacturer’s original engineering design intended it be endowed with.
Our diesel fuel injection system service and repair is designed to improve the diesel engine’s potential to maintain proficient emissions reduction and fuel economy. Other systems do contribute to a diesel engine’s final ability to operate with optimal emissions reduction and fuel efficiency, and Cummins Automotive & Diesel Service can address those systems as well.
We can service and repair diesel fuel injectors; or we can replace them with rebuilt or new diesel fuel injectors. The rebuilt injectors which Cummins Automotive & Diesel Service installs, pass independent testing of injector levels of internal timing and injector fuel delivery of through-flow volume at RPM loads, thereby ensuring they pass manufacturer specification standards. We also service the common rail when doing so can enhance the fuel injection system’s potential of maintaining or restoring the emissions reduction and/or fuel efficiency of the truck’s diesel engine.
GOVERNMENT’S STRICT EMISSIONS REGULATIONS DROVE DIESEL FUEL INJECTION TECHNOLOGY
Over the years, as government regulations continued to put the pressure to diesel manufacturers to decrease diesel emissions, diesel engine manufacturers developed new piston designs, injector spray angle alterations, and electronically controlled fuel injection systems. These, at the time new systems, created higher injection pressures which eventually led to the development of the high pressure common rail fuel injection systems, which provided an added benefit of reducing particulate matter.
Following the introduction of the common rail technology, Exhaust Gas Recirculation (EGR) systems were developed to reduce NOx (nitrogen oxides). The ongoing government demands to reduce NOx and particulate matter, to increasingly lower levels, pushed the development to the sophisticated technologies of the Diesel Oxidation Catalyst (DOC), the Diesel Particulate Filter (DPF), active and passive regeneration, the Selective Catalyst Reduction (SCR) system, and the Diesel Exhaust Fluid (DEF) mechanism.
While it might seem that the following components are unrelated to fuel injection systems, their operation whether optimal or insufficient, do contribute to the operation of fuel injection systems. Oxygen sensors, PCV breathers, valves & hoses, carbon vapor canisters, purge valves, smog pumps, air injection pumps, direct fit catalytic converters, and more; all are important components in diesel truck emissions systems especially in regard to their contribution to the proper functioning of today’s diesel fuel injection systems. While servicing your fuel injection system, Cummins Automotive & Diesel Service can check these other components for you, to make sure they are in good operating order.
In 2003, the 3rd generation of the Dodge Cummins diesel engine began powering the RAM 2500 and the RAM 3500 model pickups. Though the body style was very similar to the second generation’s high hood and low fenders, their design improvements included a new frame and a new suspension to support a heavier and more durable sheet metal body. The 2003 Cummins diesel engine was introduced with common rail injection, and it generated 305 hp and 555 lb.-ft. When the 2004 High-Output Cummins 600 was introduced, it generated 325 hp and 600 lb.-ft. torque.
Have you been thinking, “My 2003 Dodge RAM Cummins 24-valve diesel engine isn’t performing well”, or has it still been showing out true to form? The Cummins 6.7 Liter 24-valve diesel engines with Bosch injectors use the VP44, high-pressure, Bosch fuel pump rather than the “P Pump” (P7100). As you may know, the VP44 fuel pump is less reliable than the P7100 fuel pump. With these earlier fuel pumps, the rotors were poorly machined and the lift pump may have provided less than the optimal amount of fuel to the injection pump. With diesel fuel also acting as a lubricant in diesel engines, if the fuel flow is reduced, an insufficient amount of fuel will cycle through the fuel pump, in turn potentially reducing lubrication to the rotor and, as a result, the rotor can seize.
The later Cummins RAM pickup truck diesel engines lacked the ability to consistently perform at manufactured specs while a maintained and serviced 12-valve, B-series, 5.9 liter engine could perform efficiently. Do you need to get your 24-valve Cummins diesel engine back up to speed? Would you like to restore your 6.7 liter, 24-valve Cummins diesel engine to its performance of yesteryear? Cummins Automotive & Diesel Service can run diagnostic tests and potentially bring it back to its former muscular stance by providing precision service to the fuel injection system, restoring its former power, torque, fuel economy, and efficiency.
DIESEL ENGINE DEVELOPMENT AND PROBLEMS FOR PICKUP PLATFORMS
If your diesel truck is getting poor fuel mileage, it may be due to over-fueling injectors. With injection system service from Cummins Automotive & Diesel Service, you’ll get cleaned, or repaired, rebuilt, or a 6 pack of new injectors.
Does Your Cummins Diesel Engine Surge At Idle?
Have you noticed your Cummins diesel engine surge when it idles? If your Cummins diesel engine does surge at idle, there are several issues which could be the cause. The idle speed could be too low, suction leaks could be drawing air into the fuel system, the fuel supply could be restricted, one or more injectors could be malfunctioning, or the injection pump could be worn or malfunctioning. If your Cummins diesel truck engine is surging at idle, call to bring it in to Cummins Automotive & Diesel Service, and we can schedule shop space to have a certified diesel technician bleed the fuel system, take a look at idle settings, the pre-filters, the screens, check for fuel suction leaks, check for fuel suction restrictions, inspect the injectors, or inspect the injection pump.
