I have a 2006 dodge ram 2500 5.9L cummins. I've ran P2149 code I don't know anything about this. I want to know how to fix it or somewhere I can look that will show me side by side on how to fix it. Thanks

 

on top of the engine near the rail on the drivers side there are two inline plugs with 6 wires each, the rear plug is for cylinder #4,5 and 6 injectors, pull the plug off and with a ohmmeter check the resistance of each two wires they should read about 0.5 ohms. one will read over 1 ohm, it has a cracked solenoid crystal, remove and replace injector
