Please help: Smell Diesel, Runs rough then quits, lots of blue smoke wont start

[Telefrag]

Going down the road, started smelling the faint smell of diesel. Stopped someplace while my wife ran in and noticed my truck idling a little rough and sounded a little funny but didnt think much about it. When we went to leave I got into it a lil bit to see if itll clear up and it seemed to and when I went to cruise the truck got progressively worse, no power, really rought til it quit.. all in about 1/4 mile. Pulled over, tried to start nothing. Let it sit awhile and it started smooth but with a huge cloud of blue smoke, then started getting rought until it quit again. Checked the oil and I am down to the bottom portion of dip stick so its gone through a good bit of oil. Pulled my codes and had the following:

P1212
P0541
P0236

Just went out to start it and had my wife watch under the hood to see if there was fuel leak. Once I pedaled it tolife (will not idle on its own) she started seeing smoke coming from valley, and smell of diesel. We cut it got a flashlight and crawled up on the engine bay and you can see a shiny sheen in the valley.

sounds like your fuel bowl is leaking and your not keeping constant pressure
