Hey everybody! Hope yall are having a great night. I have a 2005 Cummins 3500. Found a fuel injector line leaking like crazy Tuesday while running some errands. Headed back home but didn't quite make it and ran out before making it hom . Put 10 gallons in it and got hom . Ordered a new line and installed it Thursday. Fired it up and it ran like a top for 10 minutes, then started running rough. Sounded like it had a cam in it lol ! Eventually cutting off. I could cycle the key and fire it up again but it would run for a few seconds to a minute and shut down again. I have a fass fuel system on the truck that's getting fuel to the CP3. I have confirmed I'm getting fuel to my fuel lines also. My Fass bypasses the fuel filter completely and goes straight to the CP3. Codes where 113 193 257 and 293 I believe ( dont hold me to those numbers exactly). The truck will fire rite up and run great for that little while until it gets a little warm and then start acting up and eventually cut off. Will smoke like crazy when the issue starts happening also. All 6 injectors are new within 2 months. CP3 new within 6 months. The truck has been running excellent with no issues since injectors replaced. It's just crazy that I replace 1 line and now I'm having an issue. Any help would be greatly appreciated. Thanks guys !

 

Only guess would be maybe the nut for the crossover tube backed off when you changed the injector line?

Leakage at the crossover tube-injector junction might cause the issues you are having due to low fuel pressure

Thank you Chay ! Will look at getting that tightened down to the proper torque tomorrow!
