KOEO, Do you have Battery voltage on the control wires, at the ECM?
To address the U1000/U1001, The CAN bus is a two wire bus on which most modules communicate with each other. On the bus are two "terminating resistors" of 120 ohms, each. This will give a total bus resistance of 60 ohms. At the DLC connector, Pin 3 is the CAN-L. Pin 6 is the CAN-H. If you place the leads of an Ohm meter between Pins 3 and 6, you should read 60 ohms. This is a good place to start.
