How to replace fuel injectors 5.9 Cummins 2003-2007 

That’s awesome! I’m glad you were able to do it yourself and save some money, thanks for the comment and good work 👍🏻

I got the same truck but I'm ready to straight pipe it

Thank you! I’m new to diesels so comments like yours really help!

Yeah definitely not recommend to crack any high pressure line free. Karen Boot has it down. If you turn the key on you will get 2 or 3 seconds of run time but then you bump the starter and you will get 25 seconds of fuel pump run time. I do it like 4 or 5 times and the should lite up no problem! Goo video and appreciate you taking true time to do these vids.

@@chriscollison3136 Karen boot?

Working on one right now and I’m used to the old VP 44s where you have to bleed each line spent 30 minutes trying to get the front lines to bleed because I could only get the back three to shoot diesel out but after watching this it makes sense because all the air is trapped in a common rail so you only need to crack one line to get the air out I feel kind of dumb but I’m glad I got it figured out

These people talking about stuff they have no idea what they're saying the lift pump in these are not electronic it is all mechanical besides the ECM the lift pump is mounted with the injector pump. It is gear-driven so which means it is only pulling the fuel up and delivering it to the fuel injector pump which overtakes for the lift pump and provides high pressure to the fuel rail so cycling the key multiple times does absolutely nothing to bleed this system now if you had a newer Cummins with a electric lift pump then this would be true.

So would you skip bleeding the fuel rail totally

@@chrisallen3741 yup

@@chrisallen3741 yeah that's what I always heard

Yes, you skip the bleeding because the common rail fuel system is a self-bleeding system. So, no need to crack an injector line. Like original commenter stated, it can be very dangerous. These injectors, I believe, require a minimum 5,000 psi fuel pressure to pop off and you definitely don’t want that out and about.

Im about to do this on my 5.9 and previously I had a Ford 7.3 that wanted to hydrolock if you didnt clear the cylinder before putting in the new injector. Do I need to be wary of this with the cummins?

Just had this issue yesterday

@@America-he5tzso did my grandpa

I have the same truck as you and same issues 233k miles it started I’m at 235k can’t afford injectors yet nor have an extra wheels.

Cummings? Are you watching Cummins videos again?

Haha you got it buddy! Take your time and you’ll be fine. Don’t force anything.

That’s awesome buddy!

Appreciate it 👊🏻

How are they holding up? I am in the middle of an install and noticed the new bbi stage 0.1 are not oem bosch

300,000km on these injectors and they were still fine. Only reason for the change was needing the extra power to spool the bigger turbo!

@@darkirondiesel are you happy with the headlights?

How do you know which one is bad?

It’s an aftermarket turbo, BD Diesel Howler Kit

The cp3 pump is self bleeding.. serious injuries can be caused by cracking injection lines on a common rail diesel. 25,000psi fuel can cut your hand like a laser.

Yeah I wouldn't bother trying to do it because you also lose prime if you try to do it alone

​@@wizard_of_poz4413😊😅😅😅😊

I’ve never had an issue. Wear gloves and safety glasses. Slowly loosen the fuel lines and you should be fine.

I put a bigger turbo in my truck so bigger injectors helps me to get the most out of my aftermarket turbo

@@darkirondiesel What size and brand of Turbo did you go with?

I would love to know what turbo you did as well...

Mine was cutting off as soon as I slowed down at a red light.
