2021 chevy malibu 1.5L SL
So I have gotten this vehicle at 15 miles have had it for atleast 3years it has 60 thousand on it at this point. It gave me a check engine light in about a year having it got it diagnose said it was a 02 sensor. Drove on that for a good year. Then decided to get it rediagnose to see if maybe they could erase it just because I was going there to grab more oil for the oil change I was about to do well the code came back a P10111 or something like that said they couldn't erase it for certain facts. I looked the code up said something about my throttle body needing clean so I grabbed carburetor cleaner and I disconnected my ground wire and sprayed the throttle body as well as opening the butterfly and spraying in side of it as well did my oil change put all back together and then went to start but only get a Clunk no start. Replaced the starter in which was 345 dollars WTF. But no change tested the battery came back good I'm now in above my pay grad looking for help I don't know what I should check next I'm thinking either I ****ed up a sensor or its more on the computer Hardware. Any guidance would be super grateful.

 

Welcome from Florida. Is the code P1011? This is a code for low fuel pressure. Do a fuel pressure test and check the fuel lines for leaks. You may need a fuel pump???
