The cheap $20 "ELM327" OBDII clones (see below) seem to work OK on the late model GM and VW engines in my cars.

You plug the adapter into your ODBII port and it talks via USB or bluetooth to the computer or mobile phone where you have installed the application.
If you have an Android phone grab the "Torque" app from the store (it's free) and you can borrow my bluetooth adapter. That should show you any generic fault codes but you may need to buy a more expensive hand held scanner to see manufacturer-specific codes.
If nothing else this will tell you whether your ECU is actually working. My car didn't start the first time due to voltage drop across the ignition barrel - not enough juice for the ECU. Fixed it with a new ignition barrel and dedicated relay just to be safe!
