yes you are correct. with a DMM unplug the ECM connector and check to see if C16 has continuity to ground. If it reads OL, then the problem is your ECM. I would try ebay and if you are stuck I probably have one I could sell&ship to your. if you can find parts to repair your ECM and are competent with a soldering iron then go for it.
