Never heard of that scanner. You sure it isn't just ment to display error codes and that's it? How much did you pay for it.

Please dont type in all capital letters.

I just worked on a car today with the same symptoms as yours. You can use a paperclip and get codes, but hooking up a scantool would get nothing. It turned out to be the ECM itself. I swapped it with another spare, and the problem was fixed.
