Whenever checking resistance with an ohmmeter, ALWAYS denergize the circuit. If you tried it with the engine running, you'd smoke your meter and possibly kill yourself.
The injector circuits run in excess of 100V.
To check your injector solenoids, disconnect the harness connected to the outside of the valve cover gasket. You'll see 9 pins on the gasket itself arranged like this:
G-G-I-I-C-I-I-G-G
G = glow plug
I = Injector return
C = Injector common feed
Put your meter on C and each of the I pins in turn. What you're doing is measuring the resistance of the valve cover, the UVC harness and the injector solenoid.
