2006 cobalt 2.2. Car doesn't have an issue with idle, acceleration, or rpm fluctuation, no CEL. But I noticed my fuel pump buzzing sounds like it cuts out intermittently or is on its way out. I took a video and how it shows but can't figure out how to attach (n00b). Any ideas? Try fuel filter? Or does the pump just sound to be almost done? Or leave it be until I get stranded haha? It'll be buzzing (working) and then intermittently stop and flicker off and on buzzing. I searched and couldn't find much about it. Any quick comments would be helped. Got 104500 on the clock. Auto transmission.
