The engine running on after you have turned the ignition of is dieseling. Dieseling is usually caused by hot carbon in the combustion chamber igniting the gas causing the run on. If the engine is burning oil it will build up carbon. I looked at your previous posts and you have indicated that that there was a blueish white smoke from the exhaust. Is the smoke continuous? Did you ever do a compression check?
A bad fuel pump could cause the engine to run lean. A bad fuel pump usually doesn't suck oil out of the crankcase, it pumps gas into the crankcase. I don't see that you have a PCV hooked up, so I wouldn't think your sucking oil out of crankcase. If it's not leaking oil, then it's sucking it pass the rings. How many miles do you get to a quart of oil?
What do the plugs look like? black and oily.
