NX5510 will crank but not start..

Well, that's more odd than not starting. Wonder if it's a programming thing with the one cylinder. Did they find the low compression when they were troubleshooting the ECM, or did you notice a lack of power and take it back to them?

The tractor would not start at all. Had to be pushed on the trailer to take it to the dealer. After the computer was replaced there was a "knocking." Compression testing showed the 3rd cylinder with low to no compression. I assume that the computer going bad may have sent to much fuel to the cylinder and "washed" it out. Time will tell.. I do not make my living farming but after 4 weeks if I did I would have starved to death....

Having it out for a month sounds like a dealer issue. I know there's two sides to every story, but it wouldn't be acceptable to me to have anything at a mechanics for a month, no matter what the story is. Seems like it should take a week at most, and that's getting the part direct shipped to them.

I know it's an old thread but what happened with it I have a 2016 nx 5510 that won't start and has bad compression on cylinder 3 as well

How many hours?

Do you recall the frequency of regens? I'm thinking that if there's over-fueling going on that regen frequency would be abnormally high: also potential DPF clogging issues.

Starting to think that periodic oil tests might not be a bad idea (oil would likely show higher than normal fuel in oil).

I've got 670+ hrs on mine (also a 2016) and so far no signs of engine issues.

1940 hours will start after cranking a while and for for a few seconds
#3 has very low compression 1 and 2 both over 400
Dealer could only find code for fuel rail pressure sensor
Tried 2 different new ones no change. I'm begining to think computer issue

Hey folks...

Need some guidance.. 2017 NX5510 approximately 200 hours will crank, but not start. Would not start. Then replaced fuel filter with new fuel filter. Lines cleared and will pump fuel to the injector pump, but that's it... Any ideas.

Thanks,
