My 2012 Malibu will intermittently crank but not start. No codes are being thrown and if it sits for about 45 minutes it will usually start. I replaced the fuel pump and the relay in the trunk but still having the same issue.
Thank you, that will help our members to help you better.
I could also be helpful if you'd share how many miles are on it and what kind of maintenance or repairs have been performed, such as coils, spark plugs, oil control valves, etc.
Since you replaced the fuel pump, what pressure do it get to when you turn the key on and let it prime the system, what pressure when cranking, and what is it when it's running?
