Yeah definitely try running the saw with the clutch cover and bar off to see if you are getting any flow. Like philbert said check to make sure the filter isn't plugged. If all looks good there the plastic oil pump driver could be stripped, a very easy fix. If you need help with any of it let me know, I don't live too far from St Croix Falls.
Could you post pics or a description on how to get to the gear? I'm working on cleaning out the oil reservoir now so that I can look at the filter. It's in the tank right?

FYI - MS390 Owner's Manual (OM):

Service Manual (SM) and Illustrated Parts List (IPL) can be found in the 'Beg for Manuals' thread here on AS, and they are good to have. Actually, I just found them by Googling "STIHL MS390 IPL" - send me a PM with your e-mail address if you cannot find them.

Here's the 3 stihls I got at a auction I posted about earlier for $50. The 830 j-red that came with them is gone, traded it for some 046/460 spare parts at the local shop.
First up is the 019t, this one has the less-desirable single-adjustment carb on it. I also dropped it on the driveway, which is why some of the fins are missing by the muffler. Other than it being dirty it doesn't apper to have seen much use.

Here are the 026 and 260 in boxes and coffee cans. The 260 has a cooked piston (scored on the exhaust side), so I pulled the cylnder looks like it can be saved and the bottom end seems to be ok. As for the 026, the top end is still good but beond that I have no idea about the bottom end as I didn't pull the cylnder. The 026 has the wt 194 carb as well. But both were the plain jane non-decomp/non adjustable oiler saws, all major parts and covers are there, might be missing a few small parts/screws. The 260 is a parts source for my 260 pro, the 026 I might tinker with and see about getting it going again, maybe as a cookie-cutter/fun saw. There was also a serviceable 20" 3/8" .050 bar, a 16" .325" .063 bar, and chain a a 14" 3/8lp bar and chain for the 019t in the boxes as well.

The plan now is to saw the logs into cants on Thursday afternoon. Need to have a couple extra sets of hands for help if we can. Let me know if anyone is available.

I'll try to get Jake up there as well as myself.

Yup, its I'm the tank. To get to the oil pump drive gear you need to pull the clutch off. First pull the e-clip off that holds the clutch drum on then slide the drum and bearing off. The clutch is threaded to the crank with backwards threads so turn counter clockwise to remove. I usually just give it a couple quick blips of the trigger on the 3/8 impact. If you don't have air pull the sparkplug and run a piece of rope into the cylinder to take up space and use as a piston stop. Then you can remove with a wrench. The oiled gear just pulls right out then.

Andy don't you mean clockwise to remove the clutch?
 
Yeah I'm sick as a dog. Can hardly tell the difference between clockwise and counter- clockwise right now. Thanks for catching my slip mojim, hate to see a fellow twist the end of his crank off because of incorrect advise. Got a nasty head and chest cold going. It sucks.
 
To bad you guys are a little far away, we could have some chainsaw races at my house for a few weekends. lol, just got this load today.

A few weekends??? I bet we could have that pile cut and split in about 3 hours. I remember when we cut for that fellow in Dresser, WI. He had about 2+ times that much, we showed up about 8 am and were done by noon and we also hauled it. I wouldn't have believed it if I weren't there myself. It's amazing how much work can be done when you get a bunch of firewood hacks together.
