Fuel injector
Is there anyway to check the fuel injectors without removing the valve covers

What are you trying to check them for?

Performance wise, you can only properly check them with an IDS while in the vehicle.

You can do a buzz test if you have the software otherwise you can unplug the connector and see if the engine sound changes if not that you most likely have a failed injector.

If you have the equipment run a relative compression test to confirm the cylinder is healthy. If it is good you probably need a new injector.
