Order of inspection
P0268 Cylinder 3 Injector Circuit High Medium
The P0268 code means the control circuit of the cylinder 3 fuel injector has a higher voltage than the computer expects, normally from an open circuit or a short to voltage. The injector does not open, so cylinder 3 gets no fuel. A disconnected connector is the most common cause.
