TamerX Diesel 14mm Fuel Injector Cap/Block-Off Tool for 5.9L Dodge/Cummins (Individual)
TamerX Diesel 14mm Fuel Injector Cap/Block-Off Tool for 5.9L Dodge/Cummins (Individual)
This package includes one (1) Cap/Block-Off Tool. The TamerX Diesel Fuel Injector Cap / Block-Off Tool for 5.9L Dodge/Cummins is a toolbox essential for everyone working on common rail Cummins fuel systems. When a Cummins common rail engine fails to start, your first troubleshooting step should be to check fuel rail pressure. If the pressure is under 5,000 PSI (on a 5.9L engine), the most likely culprit is a defective diesel fuel injector returning excess fuel back to the tank. A return flow volume test will allow you to determine if excessive fuel return flow is the issue. To identify the individual cylinder that is at fault, you will use this cap/block-off tool. The diesel fuel injection line is removed from one cylinder at a time and the cap is then installed on the fuel rail in place of each injection line. When the bad injector is blocked off, the fuel pressure at the rail will increase and your engine will start. In some situations, it can be useful to have multiple block-off tools, because multiple diesel injectors returning a small amount of diesel fuel will display the same symptoms as an individual diesel injector returning an excessive amount of fuel. The diesel injector cap tool can also be used for diagnosing engine knocking sounds that could possibly be caused by a diesel injector or a single cylinder issue, especially on engines where you can't use a scan tool or if a scan tool is unavailable.This injector block-off tool is appropriate for the following applications: MAKE: Dodge ENGINE: Cummins 5.9L (Common Rail) YEARS: 2003-2007This tool will also work on other vehicles with a 14mm fuel line nut.

AccurateDiesel 5.9L Cummins Diesel Injector Block-Off Tool / Cap
AccurateDiesel 5.9L Cummins Diesel Injector Block-Off Tool / Cap
When a Cummins common rail engine will not start, the very first thing to check is fuel rail pressure. If the pressure is less than 5,000 PSI, one of the most likely causes is a defective injector that is returning excess fuel back to the tank. A return flow volume test will verify if excessive return flow is the problem. This cap is then used to identify the individual cylinder that is at fault. The injection line is removed for one cylinder at a time and the cap installed on the fuel rail in place of the injection line. When the cylinder with the offending injector is capped, the rail pressure will rise and the truck will start. In some cases it can be highly advantageous to have multiple caps, because several injectors that return slightly too much fuel can have the same effect as a single injector with extremely excessive return flow. To purchase a complete set of block off tools, please see our other Amazon listings. The injector block off tool can also be useful for diagnosing engine knocking sounds that may be attributable to an injector or a single cylinder problem particularly on engines where this capability is not available through the scan tool, or a bi-directional scan tool is not available. At least one of these would also be a great addition to the glovebox kit of every Cummins owner. When an injector malfunctions on a common rail engine damage to a piston or cylinder can occur very rapidly. When a common rail engine begins to misfire and blow excessive white smoke, the owner is highly advised to turn the engine off and call a tow truck to prevent major engine damage from occurring. An alternative would be to temporarily cap the injector for that cylinder for a short period. When working on high pressure fuel systems, always educate yourself first by reading appropriate factory service information, use common sense, and, above all, WEAR SAFETY GOGGLES!
