Driving home the other day in my 98 k1500 pu 5.7l when she just died. Had an p0122code on scan. I adressed that but as i believed there was a fuel issue. I have a no start situation now. Seems my fuel pump is running, i can hear it dumping in the tank, but no pressure on the schrader valve. Is this a sending unit failure or a pressure regulator issue? The pump is 6 yrs ols rebuilt with delco parts kit. The FPR is original i bet. Any ideas are helpful
