Q: Stoped while driving on 1997 Saturn SC2

Was doing 55 and it just died. Battery, alternator and controll module all test ok. Timing chain is ok. When I try to start it. The car just clicks. When I try to turn the motor by hand it turns but it takes a little muscle to turn. Again the timing chain is ok.

Any ideas what to try next. I don't think it's the starter because it died while driving.

Where is the computer on this car?

A car needs spark, fuel and compression to start. You said turning over the engine it is a little difficult this is probably as the cylinders come up on the compression stroke the compression is offering resistance. Check for spark at the spark plug by removing a spark plug wire and holding the plug wire near a good ground and get a friend to crank over the car, see if you have spark. then get a friend to crank over the engine with a fuel line opened at the fuel rail to see if the fuel pump is sending fuel to the engine. After that the engine has sensors that are critical to tell the computer in your car how much air is entering the engine and where components are in the engine at any given time (camshaft and crank shaft sensor) these sensor inputs are needed for the computer to control spark and fuel. Failure will stop the engine from running. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subrcription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try

Sorry, I'm not a mechanic, but my car stopped while I was in the middle of driving too about 55MPH. I didn't think it was the starter either, but guess what? It was.
