Hello I'm not getting any fuel to any of the fuel system I have replaced the lift pump and all filters and I also replaced the upper filter housing and pressure regulator due to having a lot of fuel return. Before it stopped getting fuel it would start and run but seemed like it kept running out of fuel. So I replaced the pump and filters. And still had the same problem. I tried to bleed the air out of the system but coyget it all out as I couldn't even get the upper filter to fill completely. Now if I cycle the key I don't get any fuel but the pump comes on. So ireplaced the entire pump and filter assembly again(conditioning module) and am still having the same problem. No fuel. I'm starting to think that maybe my fuel pick up in the tank is broken my fuel level is 7/8 full. Any help would be greatly appreciated.
