No fuel pressure. And cant hear fuel pump run have back seat out of car. And dont know what terminals or color wires provide 12 vots dc to pump. When I meaure voltage accross quick connect pump plug at fuel pump. I do get 12 volts with key on. Just want to make sure on the plug on the ump which termianals to measure voltage. Schematic would be good. Think pump bad. But want to make sure. Thanks

Ok. Here is what me and my dad did. Hyundai accent 2000. Pulled rear seat out of accent. Pulled out black plate in floor board to expose wireing and quick connect hoses to pump and fuel filter. Changed fuel filter. And removed hose from fuel regulator and applice 12v dc to AUTO 7 FUEL PUMP MODULE ASSEMBLY, -- Electric; 11.9 gallon fuel tank capacity; An OEM quality fuel pump at the test terminal in the fuse box engine compartment near fuel pump realy. And pump runs. But I noticed that the fuel was just recirculating back into the pressuere relief line at the tee. The fuel filter was cold and the relief line was cold too. Then I blew air in the fuel line at in before the pressure regulator. Between the regulator and the fuel tank. And it was hard to blow but air came out and was clear. Then I took the line off the fuel filter and plugged in the pump wiring. Had my dad turn the car over and pump dribbled gas into 2 gallon gas can. Like it was 5 psi or 10 psi. Not much came out of pump directly. Shouldent pump put out 35 to 45 psi? Well is this common for pump to fail?
