You may have a bad fuel pump.... Or ou may be lower on fuel than the gauge reads... More on this thread here:

G210 is a fuel level sender located in the small inner housing, which always must have some amount of fuel inside itself. If you have to wait 20secs, that's the time needed for the fuel tank pump to fill that little inner tank with proper amount of fuel. For older cars, if you start the engine before that little fuel housing is filled properly, you will have yellow warning light (coil-shaped) start flashing 25secs after the engine start. This is for the older cars. For your car, you can't start it at all until that inner housing is filled with enough fuel. So, I suppose there is some problem with the inner housing, or electric fuel pump or some hose loose or some gasket leak in there...
