My 2006 Chevrolet Silverado 3/4 ton with a 6.0L V8 (LQ9). Has no oil. But it seems like it's not getting gas. Or it's an electrical problem. Truck barely runs, what can this be?

It can't run without oil pressure. It shouldn't run without oil pressure.

The electric fuel pump gets power from 3 sources, the fuel pump relay when starting, an oil pressure sensor when running and a test connection.

Figure out the oil pressure problem first.
