I would say that your 150 ohms is a problem. The wiring for the sensors does just run right to the computer, so I would just overlay it.
Start by finding all the connections in-line with the circuit. I know there is at least one where the injector harness plugs into the engine harness. Then test each leg individually to find the problem. It might just be a bad connection.
I had no fuel pumps and an open on the leg between the relay and the inertial switch. I started unplugging things to test the individual legs, no problem found, put it all back together and it worked. That was the same situation as yours, I knew the vehicle the wiring cam from ran.
