Ford injector pump failure
The injector pump in my 2009 F250 failed and fouled the injectors. 22 day out of extended warranty and Ford won't pay. Has anyone had similar problems and how much can I expect to pay to have it rep...

Believe so. The CP4.2 on the 2015 Dmax physically looks different than the one used on 2011-2014 trucks. Failures rates on 2015s seem lower (have only seen 2-3 reports) but hard to compare since they don't have a lot of miles on them.
Ouch! Just from memory, believe Ford had said that the stroke was longer on the improved 2015 CP 4.2 pump.
I was hoping that this meant they had finally put a connecting rod pin into the thing so the pump piston could NOT separate from the rod and pound the piston into oblivion.
The cp4 pump still uses a spring to push back the intensifier piston just like a cp3 pump does
