My 2006 Colorado had the same message shortly after I bought it. It turned out to be a short in the throttle body.
2007
a vac leak
check crankshaft sensor sensor
Check your alternator switch , I had the same problem before , it was loos ..good luck
I just spent $108 at the auto mechanic to find out it was my 10a relay fuse.
It sure can.
Could be a bad battery or starter.
No power available.
A loose timing chain can cause the 305 h to jump time. with improper time, the engine will not start.
Start with the lack of freon.
Cheak fuel pression in the morning.
will a bad crank shaft sensor make a 2005 chevy equinox not start
