havent found anyone who can test them either, I have same problem. everyone is willing to sell a new reman though. did you test voltage at valve cover connectors center pins with key on? I think it should be around 110v from what I have been told. maybe someone else can verify that. mine has 0v so im pretty sure its shot.

Icp?

Unplug sensor on front of driver side head and see if it starts, CEL will be on but mine fired right up. Almost bought IDM today, glad I didn't.think it is called the icp sensor.
