Rail pressure relief valve??
 

need some help bad i got a 07.5 6.7 and put a new set of injectors in it and new injector wiring harness now the only way it will start is to pull start it and as soon as you go to drive away and then stop it dies wont idle could my pressure relief valve be shot? need to get this pickup on the road bad

Buy a rail plug and see if that fixes it cheaper then a relief valve if it dont help when it does start is it a complete dog? No power? When i priced a relief valvr from cummIns they wanted like 4 or 500 so i plugged mine been that way for 4 years

yes it is doggy as hell cant get over 55 has no balls whats so ever and thank you that is what i was planning on doing just wanted to hear it from someone else if i should or not and ya i priced one and thats when i decided to go with with plug do you know were you can get one off the top of your head

There are lots of great vendors on this site. Looks like he got you hooked up. But i buy most of my products from tony @ mighty diesel : 877 354 7008. Hes a great guy if he cant get it he will find it. Good luck:c:

I am very surprised that someone has not come out with a relief valve that has a stiffer spring. Shimming is ok but a exchange for one with a stiffer spring would be nice. From what I read you take a big chance if you plug it. it most cases it is fine but if you get a big spike you may be buying new injectors. I am having problems with mine under heavy load so I bought a shim kit and it should be here monday.

i have heard bad about the rail plug . but i have been running mine for at least 60k with no problems what so ever

You are asking for trouble with a plugged rail, and yes - there is a company making rebuilt PRV's. It's been a couple years ago I saw that somewhere, sorry can't give any specifics.

i have seen dozens of plugs running around. i have only heard bad on the internet. :hellox:

im not saying its not going to fail something.
what i am saying is i got 60 thousand miles. with out a single prob i have heard bad on the net only but not from experience or anyone that it has happend to. i drive my truck like a stock car. i pull trailers grossing a touch over 20k all the way down to car trailers. and hasnt exploded yet. :tu:
