I have a 4.3L v6 with CMFI VORTEX engine.I have a fuel issue.I have replaced the electric fuel pump assembly and relay.I can here the pump working and I get fuel flow thru the filter.I know the truck has spark and will run on starting fluid. My question is where is the regulator (fuel pump) and what does it look like?Will this cause the engine not to run? I do have a shop manual for this vehicle, but it"s not to helpful on location and function of this regulator. PLEASE HELP.
