With zero indication that it was going to shut off. No knocks no ticking no sputtering like it needed gas nothing. Now the hatch light wouldn't go off. So, I assumed the battery probably drained. Tried to jump it and it cranked but will not start. Suggestions?

Hi,

In most cases, the cause of a crank with no start is either a loss of fuel or an ignition spark to the engine. However, this vehicle also has a timing belt that can fail. If possible, record it cranking and upload it for me to hear. I should be able to tell if that is the issue.

First, does it sound normal when cranking the engine? If it does, then see if it will start if you use starting fluid. If it starts and then stalls, we know it is a fuel-related issue. If there is no change, then the ignition spark needs checked.

Here is a link that explains how to check for spark:

try this and let me know the results. Also, pay attention if it seems the engine is turning faster when you try starting it, and let me know your thoughts.

Take care,

Joe
