This is another problem that really needs the services of a diagnostic computer to make any sort of meaningful assessment of what’s going on here. That said, this engine uses a throttle-position sensor to turn the driver’s right-foot input into forward motion at the engine. If this sensor is not talking to the on-board computer, there’s a good chance you could have the exact condition you’ve described, Shalvesh.
On a more fundamental level, are you sure the transmission is selecting gears? Perhaps the vehicle is stuck in neutral somehow. But if the engine won’t even rev up when you hit the throttle, I think you’re looking at some kind of sensor problem.
