The first thing you may notice is the engine will become hard to start. You may also notice gasoline mixed with the oil as the diaphragm in the pump may have a hole in it allowing fuel to enter the engine oil pan. Eventually the engine will not run at all from lack of fuel when the pump fails completely. You can test the pump by removing it and pushing the lever on the pump all the way in, then put your finger over the inlet and release the lever. If the diaphragm is busted the lever will move back. If the lever holds steady as long as you have the inlet plugged the pump is good.
