New to me 2015 suburban with around 150,000 miles, ticking noise develops shortly after startup, no misfires but I do have a check engine light on with rich codes for both banks (assuming Hp fuel pump) what are the odds that the fuel pump is also making the tick/tapping noise ? Doesn’t seem to be coming from any accessories on front of engine.
