A very nice customer came complaining of a fuel smell after driving and poor acceleration. He was thinking fuel pump. After confirming nothing physically was leaking I hooked up my fuel pressure gauge and saw there was a drop in pressure once the key was turned off. Starting with the basics I removed the spark plugs. (Cylinder 3 was soaked) I used my scope and looked for a constant mist. Found it in cylinder 3 so unfortunately there is a leaking fuel injector. Much better than a fuel pump.
