Asked by for the 2003 Pontiac Grand Am
what symptoms? No spark ? No fuel? Timing?
Car turn over but won't start. I have not checked for spark. Car has fuel. Timing are you referring to the timing belt.
Ignition timing , but knowing if the timing chain is still on properly wouldn't hurt, if it's easy for you to check.
