Find the fuel filter, take it off-install pressure gauge-turn key ON -read the gauge-dunno the specifications look it up in the book. You're looking for excessive pressure or injector problems. FYI anything can cause high consumption-alignment, brakes, slipping tranny and no upshifting, valve train, loss of compression, faulty ignition system.
To really get to the problem-check the compression and go from there-check every subsystem within the vehicle.
