sometimes when it is cold outside, maybe in the low 30's or 20's, the truck has a hard time starting. Sometimes it will start and then go dead. It did this 3 times one morning. The 4 time I got on the pedal and it stayed alive??? The other ongoing issue is the hard starting. I have been back to the dealer 1000 times for the new flashes and it still turns over more times somedays than others. I am just not sure if it is going to start when I get in or not. I have noticed some fuel on two wires below the cp3, like it is leaking. Could it be losing its pressure on startup and that be the problem? Reliable cummins, ha!!!

 

Its not the Cummins dude unless this all came as an option ...

Bullydog TripleDog with Outlook Monitor, AEM BruteForce Intake, Silverline 4" Duals, Quadzilla Boost Fooler, BD AUX Lift Pump, BD Super B Single Turbo, Autometer Boost Pyro Tranny Gauges, CFM+ Intake Manifold



Most hard Starts are from the Fuel Pumps ,IIRC too much fuel when starting

If you see Fuel then your Also Sucking Air which isnt helping .

Disconnect your Bully Dog and Test your truck out for a few days to see if it went away

 

still does it without bullydog. I've had it off for bout month, the new update seems to have lot of low end power and response is great so I kept it off, and it still does it every now and then. And the aux fuel pump doesn't kick on until the oil pressure is at normal level. Anymore suggestions???

 

you showin any codes????

 

Take it to cummins and see what they say. I've been to some dodge service centers that almost couldn't tell the truck was a diesel.

 

Can't do it. Cummins won't work on 3rd Generation trucks. A squabble between Dodge and Cummins cause Dodge won't turn over the electronics info and programs for Cummins to be able to work on them.

 

Well thats pretty sad. It's hard to believe Cummins can't work on their own engine but being Dodge I guess I believe it.

 

Rail leak down or injector leak down would be my bet if it were a consistent problem. Could be a Grid heater voltage problem or as stated , to much fuel. Treatment should help!

 

what do you mean by treatment? Injector cleaner? No there isn't any codes.
