Ok, I think it may be time to look at actual wiring diagrams and start measuring voltages. If you don't have a meter, a 12 volt trouble light will do just as well. In the following link toward the bottom are diagrams to the ECM. You will have to join the group to be able to open the picture files.

Also, a Google search on "16197427" brings up tons of info, as it is one of the favorite ECM's to use in custom fuel injection systems.
One other question, when you turn the key on, does your check engine light turn on? If it doesn't, you do not have power to the ECM.
