2014 Chevy misfire issues

[Marshgoat]

Check engine light come on? Don't take this the wrong way, but you sound like a Chevrolet service advisor. It's ashamed but the dealers cant do much if anything at all without a check engine light illuminated. Not once has my light come on. Actually had the engine die on me twice at a stoplight. Turn the key off and then restart and it runs fine. I am convinced the issue with my truck is the high pressure fuel pump on the engine. When I say mine is 3 times louder than any other I really mean it. I have had people ask me if my truck is a diesel in a half ton. The ticking of my pump sounds like a kid beating an empty pie plate with a metal fork. All 3 dealers say its one of the loudest pumps they have heard but GM will not allow them to change it. There is no spec for noise so its "working as designed" !!!!
