MY VAN HAS RECENTLY STARTED USING AN EXCESSIVE AMOUNT OF GAS.THERE ARE NO LEAKS IN THE LINE OR TANK. CAUSES?

1999 Chevrolet Venture • 244,000 miles

The van is using almost twice as much gas as before. The gas gauge does not work so I always do the calculation and have done this for more than a yr with no problems and now I am constantly running out of gas. I checked EGR valve and it is not sticky. But I could not check with an ohmiter. What could be causing this sudden problem?

Give it a major tune-up

Check the fuel pressure if its within specs-Reduced mileage could be caused by tires/wheel alignment, brakes, transmission etc!
