My 07 Cobalt won't start. Engine turns over but won't fire. There's spark and fuel. There's a small rattle at the front. Is that a broken timing chain?

Asked by Oct 21, 2013 at 12:10 AM about the 2007 Chevrolet Cobalt LS

Question type: Maintenance & Repair

The car never ran when it started making this noise. It's a small rattle when cranking at
the front of the engine. I know these are no tolerance engines. Should I be worried about
the valves droppings?

Run a compression test. If all cylinders are low or no compression then it's jumped timing or, as you hinted to, a broken timing belt or chain. HTH. -Jim
