I recently put on spark plugs and coils within 24 hrs the car cut off
I was told the converter went out but not sure which one.  I had gaskets cleaned and the exhaust closed and was able to drive it without it being loud.  Now I don't know what is the problem the car will  not start.  I was also told I had a valve cover gasket that needed to be replaced.
Vehicle: 2009, GMC Acadia 3.6 engine

P0011 Intake camshaft position (CMP) system performance Bank 1

P0024 Exhaust camshaft position (CMP) system performance Bank 2

These 2 codes are for the camshaft position solenoid malfunctioning, it will not cause a no start condition, You going to have to do the basic for the no start condition, Even with these code preset the engine would still start it will not run right but it would surely start. The basic has to be checked such as ignition, and the compression. as well as fuel pressure.
