A mercury truck,Mountaineer AWD V8,4.0L is running on one bank with the 4 injectors functioning while the other bank injectors not functioning at all. I have Checked and found out that there's no ground from the pcm to the injectors. What could be the cause of this?

Sounds like you need to check the injector themselves, one might be shorted, or the driver inside the computer has gone bad, its rare but it happens.
