2003 randomly stalls, no check engine light
My moms 2003 galant 4cyl randomly dies. Sometimes it can start back up right away, and sometimes it just cranks for awhile, but let it sit for 10min or so and it starts back up every time. A few months ago she lost her timing belt and very surprisingly it didn't bend any valves. I replaced the belt, seals and a new oem crank sensor. The car ran fine for about a month before it started dying. For some reason she doesn't have a CEL. Even when her timing belt broke there still wasn't a CEL. I checked when i insert the keys into the ignition and turn it to accessory, and the "service engine soon" light appears, but goes away upon starting the vehicle. Any ideas what could be wrong with her car?
