Hey guys new to the forum but I have a problem I'm hoping you can help with I have an 06 ss/sc with a 3 inch pulley aftermarket injectors cold air intake and a 3" srs catback and she shut off one day and I left her for a little bit the managed to drive her home and now upon start up she will hit 2k rpms but the drop until she almost shuts off and will catch herself sometimes I've cleaned the maf, and checked/cleaned the throttle body (seemed fine), replace the air filter since it was verrry rusty with a k&n,done a fuel pressure test and found she was loosing pressure over time so thinking it was the pump I went out to a scrap yard and got one plus a new fuel filter but now she seems worse then before I can't touch the gas without her shutting off and she makes a weird whine as she shuts off but only when my foot is on the gas, the whine seems to be coming from the front so now I just want some opinions before I start going through replacing all he sensors $$$$ lol thanks guys will post a video if needed ***also replaced plugs And put stock injectors back on***

Also the battery was out of her for a little while and I can't get a drive cycle out of her to see if she's throwing any codes, since replacing the pump it makes a weird whine coming from the intake
