Re: 98 C1500 5.7L Fuel Pressure (Won't start)
you need 60-65 psi. pinching the return line for a short time it should shoot up quite a bit.
the fuel pumps require 1/4 tank of fuel or more to keep cool. running below 1/4 will cause pump failure.
replace relay and filter. replace filter every 30,ooomi.
make sure the ground at the fuel tank frame rail is removed and cleaned.
