Got the motor in, Full delete everything is gone! New EFI Live tunes loaded and no start?! Cranks over fine just not firing Cracked lines has fuel at tubes. Checked everything several times and nothing Has new batteries and NO codes! Going to try either tomorrow! Any thoughts before I spray it??
 
What is actual fuel rail pressure while cranking? I’m going with my normal of it being crossover tubes.
 
Turned out to be the fuel system on these trucks do not purge themselves! I had to crack the lines to release the air. then a quick shot of either to make it spin a bit faster and instant on! Runs like a kitten. Now have to drive it 2 300 miles mildly for the trans to relearn everything damn these trans suck!
 
I’ve never had to ether anything on a new build other than a pulling motor
Especially not a common rail

You own a diesel repair business, OP?

I'm curious if it has restarted from a cold soak yet.

He obviously does work on the side, with every problem he has, he runs here looking for us to bail him out.

I do this on the side to help out my fellow Cummins enthusiasts! First time replacing a 6.7
the 5.9 is a breeze to start! Bre go pack sand I come here to ask people for help when I need it and give it when I've had their problem. You are here to be a smart ass probably a troll on other forums and a live at home diesel wannabe. Comp D is for knowledge shared by a bunch of guys that love what they do!
 
Biggy sat overnight instant on love it! trans on the other hand should be banned from existence!

Yeah, no...CR shouldn't have to crack crap to bleed...We do it all the time on tractors, swap parts and start them...

I'm curious if the low side fuel system needed to purge.


Don't ever crack CR lines for bleeding again. Please.

Bre just going from your picture! What shoul;d I think......It's a joke BRO!
As far as the cracked lines I thought the same thing NO WAAY but the tuner said try it Idle is 5 7k so cranking maybe 2 3k But when I cracked them they only gurgled out air and then a steady stream no pressure. talked to a friend and he see's this a lot led me to the quick shot of either to spin it a bit faster! so all good learning curve!!
 
anyone messing with ether isn't messing with my truck or tractors....if its right itll start...not like yer pouring gallons of fuel in an open class puller
 
Lots of Piss & Vinegar!
That always cures the problems, eh? :D

I had a 2006 a while back that had a broken number 4 line and had sat for a year afterwards.
Replaced the line, did every trick I could to get it to fire, would NOT bleed the system.
Took just a mild whiff of ether and never a problem afterwards...
Until the starter died, which was the whole problem.

I found that the ECMs need to see a certain cranking RPM, plus a minimum pressure and air in the system tends to mess up that equation, sometimes.

So will weak starters, batteries, or bad connections, or even a tiny fuel leak. :mad:

Mark.
 
Hahahaha hahah I typed a post the other night about CATs and engine speed and then deleted it.
I cobbled a C10 cat into a C12, started it with ether and it checked OK, so I sent it to the customer (on a stand). They installed it and it would not start.

The there was a serial number split for a different style tone wheel. CAT starts on the crank sensor, and runs on the cam sensor.
Cummins isn't this way. By feeding it with ether, I allowed the engine to see enough RPM to overcome the component issue.
