New to this, but I got an 08 that ran p0087 and p0088 so replaced the hpfp. Now the truck doesn’t start and just blows white smoke. Started to get wrench light for p2291 (fuel injection control module low - engine crank) code. Replaced just the low pressure pump and not the whole housing. Still no start. Ive installed a gauge on the shrader valve and a bleed line. Bled a lot of air. Cracked back banjo bolt and released some air. Still no start. I’m lost because now when I crank I’m starting to get more of a black smoke coming from the exhaust. Any ideas?
