Oil, transmission fluid and antifreeze are the three fluids most likely to be the cause of white smoke coming from your exhaust. Ruptured seals, leaky bolts and blown gaskets can expose oil to hot spots, making it burn. Pinholes or loose lines can cause antifreeze to spray on the engine, while transmission fluid can be sucked into the engine and burn.

Did you check your spark plugs? Any CEL codes?

If it is running that rich, your catalytic converter will fail. Other than that, with no codes, I will have to leave this to a mechanic.

Maybe something with the fuel injection? Do injectors wear out and flow too much gas?

Are you SURE its fuel? Generally super rich is BLACK smoke, not white. Oil or Antifreeze intrusion will cause low mileage to if it is bad enough.

I checked fuel pressure before changing the fuel pressure regulator (twice) and it had zero pressure in line when i went to relieve pressure for test.it built 40psi while cranking,then dropped to 30psi while idle and 20 psi at 2500rpm. the reason i changed the regulator was after a few seconds (5-10) with the pressure gage still hooked up the pressure would slowly bleed off. i thought it was suppose to maintain so many pounds of fuel pressure in the rail.
