Check the manual to see if there is a fusible link in there somewhere. There is always a chance... If you have a voltmeter you can check continuity from the diagnostic point to the ECM pin. If you don't have continiuty then you have a blown fuse or fusible link between the 2 point (more than likely). If it rings through, then you probably fried your computer.
