pulled mine apart no pump what a shitty dealership i told my brother to make sure never to go back. so he put an air dog on and the truck is runnin fine however obviously his cp3 is on its way out but it is fixed temporarily.
It's likely not be the CP3 - it was most likely the filter and they didn't prime it enough. A lift pump will normally not fix a CP3 problem that is bad enough to keep the truck from running.
