Hi scotty. I have an 04 mercury mountaineer 4.6L the engine is not getting any fuel. And in the message system on dash says low oil pressure. We have cleaned out the tank put in a new fuel pump, fuel filter. Blew out all fuel lines. Installed a new oil pressure sensor switch and fuel pump relay. The car will crank but not start. And the engine is still not getting any fuel. Any help would be greatly appreciated!
