Question about 2005 Chevrolet Cobalt
Car wouldnt turn over this morning it cranks , checked fuel, chcked spark and timing chain, i have spark but no combustion
The spark has to be blue and strong. If it is a weak spark, the coil , rotor, or cap could be the problem. Check the coil with a duplicate or have it checked. Also check the compression on all cylinders.
