Saturn sl 99 will crank but won't start

2002 Saturn ??? What model ? Vue FWD Vue AWD , SL 100 , SL 200 , L100 , L200 , SL , SC1,SC2 , SL1 , SL 2 etc......

How hot is it getting in degrees F? Some electric fans won't even turn on, till around 220 degrees F. Does the fan turn on at all?
As far as overheating, does the coolant recovery reservoir fill up in a hurry?
Sometimes after opening up the cooling system, you get air in the system that may cause temp gage to react.
What about your thermostat? Did you check for coolant flow through the radiator? Another thought might be a head gasket issue, I'd check everything else first.

Get the chargeing system check out on it,

Done cars have a kill switch if they are low on oil. Check your oil. If the oil is good, it may be the ignition switch.

96-99 SL1, SC1, SW1. Avoid the 2 models, they are DOHC and have different gear ratios

My daughter has a "99 Saturn SC1, and she hit a curb and deployed hers. I (Many years as a mechanic) replaced both bags, the computer which is located under the center console, and the "clock spring" located behind the steering wheel to get it all working. (No air bag light on while driving) The steering wheel airbag melted the clock spring when it fired. I purchased these all used on E-Bay.

the SL seats were pretty interchangeable, so i would imagine the SC seats are as well. there are only 4 bolts so it does not take long to check/

2002 saturn sc1 battery died,replaced,now cranks but won`t start

I’m happy to help further over the phone at https://www.6ya.com/expert/kenneth_3efc1f8510674f04

a p0341 code mean cam reference performance, really it means you have a secondary ignition problem,,,,like a bad ignition module
a bad crank sensor
a high resistance spark plugs,do not use bosch platinum plugs in these cars
high resistance spark plug wires,,,i work at the dealer and the first thing we do is replace the spark plugs and wires if that dont work we replace the crank sensor,if thatdont work we reaplce the ignition mondule,and by then your fixed and you started with the cheapest items first,,,i would try plugs and wires and a crank sensor,,,,wires $50 plugs $14 crank sensor $37
