2.9l wasn't known for it's oiling system lol, could be anything from a clogged oil pick up, worn bearings, clogged rocker shafts, etc. Clean the rocker shafts, do an oil change with any filter except a STP or bottom line FRAM, then check oil pressure with a gauge.
If it's low, then the pan is going to need to come off - basically it needs removed and engine will need inspected for signs of failure. Could try letting a solvent soak in the pan after draining oil (to help if the pick up is clogged, but this can also break old gunk loose and make matters even worse by adding more gunk to the bottom of the pan), just be sure to get as much of it out as you possibly can if you decide to do that.
The pan is hard to get off when it's in the truck, and it's going to be real hard to work on it trying to do it that way. I have seen an oil pump with 140K work just as good as a brand new one, they are very simple, but not entirely unheard of failing. Oil pump is assumption a lot of times, but you would just need to see if lack of oil is really causing the issue.
