I changed the fuel pump in July. Bought from cummins and it came with a selnoid. Also changed all the fuel lines and the check valve. It was hard starting is why I changed all that.

I've tried unplugging one at a time and the number 6 injector will start missing when I unplug it but it doesnt sound as severe as the rest when I unplug it. You can just tell I did.

Cummins tested cac and the intake system when it was there and found that bad intake gasket and fixed it.

You can here the turbo spool it just feels like it has no boost. The horse it has you should be able to feel it pulling a 30k lb load. It feels like I have a 330hp ism lol

This is all speculation, i have never worked on one, just repeating what has been said to me in the past ...

N14 injectors that are worth a damn are hard to get. Cummins is no longer making new stock for them from what I hear, so all you can get these days is remans that have been re-worked several times and are are slap worn to the bone. Parts for N14's are a crap shoot at best these days, the engine are no longer supported. There are also 2 sizes of injectors, make sure you have tyhe correct oens for your engine + make sure they did not mis-match them.

Mr. Hag has repaired a bunch of them in Atlanta. Maybe a trip his way at some point wuld not be a bad idea.
