Hello. I have a 97 saturn sc1. For three days this has happend. Starts just right, runs and sounds just right, rev it drive it, and its good. Then out of no where it just dies. It doesn't chugg or miss fire, it just dies. Iv checked the fuel pump and its good. Iv changed the fuel filter and switched out the fuel regulator and the map sensor. No change. And every 5 minutes or so I can start it back up and do it again. I won't leave the driveway. Does this sound like an electrical issue and or would it be fairly simple to get at? Please help.

When it doesn't start do this take two spark plug wire's that are right next to each other off the coil and crank it over and see if spark jump's from tower to tower. Let me know what you find there. Also do you have any code's?

Not that I know about. There is no light indicating there r codes. (Check engine, or service engine) none. But I will try what u say. What would it mean if it did or didn't? Fulty coils?

More likely a faulty crank shaft position sensor just because your light's not on doesn't mean you can't have code's. Go and see if they can pull any code's from your car at a auto part's store like auto zone.

No codes, no spark. Even took just a single wire off to see. And nothing. But I started it when it did start. And sparks were jumping. So if there's no spark when it doesn't start, does that point to the crankshaft sensor like you was thinking? And thanks for you help.

The most likely cause for the no start no spark would be the crank shaft sensor there 20. You could also have a bad ignition module which they hardly ever go bad and are over 100. The problem your going to have is the no start only happen''s for 5 min's that's no a whole lot of time to test the crank shaft position sensor. If you could rent a scan tool that read's live engine data then when it doesn't start you could see if it read's rpm's on the engine data while cranking it.
