In debate they call this ^ the straw man response where make it sound like an opponent is saying something they are not, in order to refute that rather than something they actually said. Sure, check the fuel knobs to see where they are, and IF you have time for a restart before ground meets airplane, and IF you suspect starvation was what originally killed the engines and it's likely to work, then by all means go for it. I would not attempt it if oil is coating the windscreen or a fire has begun or any of a number of other situations are going on. It's one option among several to weigh.
