We have had some of the same issues on some of our 2001-2002 builds. we slotted the holes in the mounting plate and moved the sensor around while the truck was running with someone inside the truck to watch the tach. I have seen them work even without the ECM being externally grounded. On one build, I mean program, we had to adjust the height of the sensor so that it was closer to the cam. I think if you play with the sensor it will probably work.
