Is it possible they could be leaking? the truck runs real good but cranks for about 10 seconds before starting, any ideas

When I put it all back together it would start fine but today it would not start, for about 10 seconds?

Great pressure at the vp44 21lbs.

Thanx

 

sounds like youve got a bad o ring one one of your flow tubes IMO

 

Im not sure what you are refering to.
please forgive me im still learning the lingo on this diesel stuff.

thanx Steve

 

ya know the lil tube you had to take the injector line off of and pop out in order to take the injector out? Thats your flow tube. you may have nicked one of the o-rings on one of them

 

Ok gotcha

I was going to pull all of the injectors anyway so when I do ill check all of the O rings.

 

id check the o rings on the flow tubes first! you may not have to pull the injectors....

i had the exact problem your describing when i installed my mach's. i knew it wasnt the injectors, so i pulled the flow tubes and i had 2 that had nicks in the o rings

 

When I did my injectors I replaced them. I got them from cummins for like $8.00

 

CTD01
Did you replace the o rings that were on the injector as well as the o ring on the flow tube?
thanx

 

Yes I replaced both.

 

Should I post everything I own on my Sig? or just the stuff I have Done to my Cummins turbo Diesel?

 

New O-rings and washers are cheap compared to the problems that one little "nick" can cause. Cummins Southern Plains in Mesquite is probably your closest place to get them.

 

we usually go to the one on Irving Blvd. the people walk backwards in Mesquite

 

Yeah most likely one of your cross over tubes is not sealing letting air through and it's try to get it out those first couple seconds of cranking. I had the same problem when i pulled the head for o-rings and a new gasket

 

I laughed... HARD!

 

me too....
