1993 Mazda mx6 2.5L 5spd. I still have the problem of not getting fuel to the rail. 6 months ago I had the fuel pump replaced, fuel filter, and new dist. Assy. After this work the car ran well. Started good one morn. Made one stop went to start it and nothing. Cranks over but not getting fuel from tank to rail. All fuses and relays are good. Did test the relay at the engine block and everything checks o.K. Have tested fuel regulator have replaced crank sensor. Fuel line is clear from tank to rail. Have proper voltage going to pump but still not pumping fuel. Tank is grounded good. I'm at my witts end on what to do next any help would be appreciated.
