LMM: trucks falls on its face

Get back there are look at the bolt head on the FPRV. Someone may have shimmed it already, but not put it back tightly enough. It's a whore to tighten it back up all the way on the LMM... usually involves double wrenching and/or a BFH.
If the FPRV head looks virgin, then shim it
Post the log here if you get a chance. Maybe we can fix the tune for you!

I am kinda having the same problem with my lmm. The other day went to 0% fuel filter and fell on its face when u get on it but my pump is soft, like its losing its prime and u have to get out and jack it off every time you want it to crank. So it could be sucking air?
My LML does that when the filter needs changed. It goes back to 0% every time I restart the truck after resetting it. The place that changes our oil uses cheap FFs, so I have to have it changes a little more than normal.
