I realize my van is old and has high miles, but until it stopped pushing fuel it ran great! It is a 94 Aerostar AWD 4.0L with almost 170,000 miles. I was out and about with it 1 day, had no problems whatsoever. No odd noises, no sputtering, nothing. That evening after driving it we had a MAJOR blizzard lasted 2 days. After the blizzard died out, I went to go somewhere and my van would not start. I have changed the fuel pump, fuel filter, fuel pressure regulator, spark plugs, wires, coil pack, crankshaft position sensor, electronic ignition was tested and is fine. It cranks but will not start. After 3 months now of checking and replacing everything I can think of I pulled off the fuel line at the filter to see if it was even pushing fuel. It was bone dry! No gas has ever even gotten to the filter. I can hear the pump in the tank running. What would stop fuel from going through the fuel line? Any idea on how to figure this out? I'm totally at a loss now. Thanks for any advice anyone has!

After redoing the fuel pump, there is still no pressure building up in the fuel line. What are the odds that 3 fuel pumps would all be too weak to push? Somehow I am just not getting pressure to build in the fuel lines but I can hear the pump run and I have used a high pressure air pump and air blows through the lines so there is no blockage. Any ideas on why/how the car will lose fuel pressure like that?

Also I am not getting any trouble codes AT ALL! I replaced my ECM, as well. STILL nothing.

(Anyone have a match?)
