My 2020 Great Wall Steed has power to everything but won't turn over or push start...

If you mean that the engine refuses to be turned over either by the starter motor or by physically pushing the vehicle in gear and then letting out the clutch, then there’s potentially something seriously wrong. As in a seized engine. Has it been overheated? Has it been run without oil? Both those things can seize an engine to the point where it is locked solid.

You stand to do more damage by persisting with this, so the smart move would be to present the vehicle at a Great Wall dealership as your Steed is still well and truly covered by the five-year factory warranty (assuming it has a complete service record and hasn’t travelled more than 150,000km. I can see that you’re from the Northern Territory, so perhaps the nearest dealership is a long way away, but if the drivetrain doesn’t want to turn at all, then a dealer is the solution.

If, however, you mean that the engine won’t fire up (but is physically turning over) even after push-starting the vehicle, then the problem might not be so catastrophic. A modern engine needs the correct input signal from literally dozens of sensors before it will run properly (or at all), and if you have a single dud sensor, that could produce the no-start condition you’re seeing.

But here’s the first thing to try: Turn the ignition on and listen for the faint buzzing sound of the electric fuel pump. If you can’t hear it, chances are the pump has failed. It’s very common and one of the typical ways fuel-injected vehicles cease to function. Even so, in a vehicle so young, involving the Great Wall dealership network should be your first step.
