Alright at a loss here. Installed the cp3 bag of parts from industrial (complete crap) truck started ran but fluttered a little. Worked it’s self out so took it on a test drive and while going up a hill died and hasn’t been the same since. Wouldn’t start so I put my stock parts back on and fired right up but stepped on the gas fluttered and died then no start again. Called industrial (customer service is trash) told them all this they insisted I send my pump for a free rebuild and test. Over nighted my pump they “rebuilt it” and promised to send me the test papers which they didn’t send with and the truck is still doing the same. Fired right up after pump install and hit the gas fluttered out died and now won’t start. Can’t here the cp3 ticking but you could before the no start. I’m at a complete loss any help is appreciated! Also throws low rail pressure code at idle when it was running
