1986 Chevy S-10 5 speed, where is my oil pump?

It's located to the rear part of the oil pan. To change it, the oil pan needs to be removed. To do this, the engine needs to be raised, or the transmission needs to be removed. Make sure it is the problem before just "changing" it.

Can't locate reserve oil drain plug on 1994 Ford E350

It only has 1 oil pan which is call a dual resreve. One oil plug is a the bottom of the pan the other is at the front of the oil pan. Look at the front of the oil pan for the other drain plug. Make sure on how many quarts of oil it takes. ( I know 5.0 take 5 quarts including oil filter. But then again its a van double check)
