Loud fuel injectors and fuel pump?
As the title mentions my Fuel injectors have been louder then normal the past little while and my fuel pump has a high pitched whine when the car is running. Is this normal or should I start looking into replacements?

Inside you can faintly hear them but only within 300ish rpm of redline. When i turn it on i get the usual hum along with the whine but they both stop after a couple seconds then when I start it the whine returns, I really don't know much of the cars history but it had an aftermarket stereo and was rewired but sold with stock components and my mechanic mentioned after swapping out the engine after the rings let go that I'm getting higher then normal fuel pressure. could there be more done to it then i'm thinking? All i know in that aspect is after passing the previous owners house twice they seem to have a not very stock chevy cruze... Also if you shift it into Incline or low gear and let the revs drop with the speed of the car it'll pop a bit out the exhaust

When I changed the thermostat recently i cleaned the injectors aswell and they're much quieter now. Is there a recommended milage to clean them at or just when they get noisy?
