So my 600k pump bit the dust...found a Cummins reman that came off running truck supposedly.. Installed pump and runs rough ...as soon as you open throttle I mean even .030 it dies... I am a tech for a living and have installed 100s of these pumps... Now I am human and screw up but before I pull front cover I would like opinions.
I haven't built many pumps so am having issues visualizing what is happening.
Thanks guys
