I'm trying to remove #5 injector and it definitely "seems" to be stuck in the head. No I haven't purchased tool #9010 (Clamshell injector puller). I am however very intuitive and was able to build something else out of another puller I had that seemed to allow me to apply Enough pressure that I thought, should've removed it.
So here's my concern, I still drove my '05' Dodge for 3-4 months after knowing the #5 injector had quit operating.
I had to change my serpentine belt twice during this time to which I chalked off as the miss from #5 cylinder not firing.
I'm very sad to think of my worst case scenario here but haven't given up hope yet.
Please offer your thoughts on what's going on and what you think about my situation....

 

If you have a good fixture to pull the injector and it still won't budge, it's time to pull the head.

Try to pull another injector, just to test your injector puller.

 

I was afraid of that!

If I do pull another injector, can I drop that right back in or do I have to do this

(2) Thoroughly clean fuel injector cylinder head bore. Blow out bore hole with compressed air.
(3) The bottom of the fuel injector is sealed to the cylinder head bore with a copper sealing washer (shim) of a certain thickness. A new shim with a correct thickness must always be reinstalled after removing injector. Shim Thickness: 1.5mm (.060�)
(4) Install new shim (washer) to bottom of injector. Apply light coating of clean engine oil to washer. This will keep washer in place during installation.
(5) Install new o-ring to fuel injector. Apply small amount of clean engine oil to o-ring.

thanks for your feedback StealthDiesel!!

 

Are you a mechanic StealthDeisel??
I have more mechanic type questions

 

Not a mechanic but been wrenching for years and wrenching on CR Cummins since I bought mine back in 2004.
Feel free to ask any questions at all. There are a ton of knowledgeable folks on this forum.


Working on the CR Cummins fuel system is not difficult. But you need to precise, take your time and keep everything extremely clean.

The steps you outlined are simple and basic. Don't take any shortcuts with the fuel system, especially on the high pressure side.


These trucks are now really getting up there in age. There is tons of on-line information for them.

Search on this forum, plus a google search.

Stupid question, but don't the CR engines have a connector tube that has to be removed before the injector comes out, like the VP44 engines?

 

Yea it does. I could only wish that was my problem. Thanks for responding

 

Yep, I figured there was more to it than that, but it's all I had.

The older engines were sure easier to deal with, having the threaded fitting on the top of the injector made it pretty easy.

Hope you've achieved success by now.
