My 1997 saturn tuns over but wont start . i have tested every sensor and they are good.

Why did you replace the crankshaft position sensor ? Vehicle has no spark ? Did you test the electrical circuit ? There is no luck involved if you know how to test. To many videos on youtube showing how to test to not being able to find the problem .

Have you replaced the starter ? That might be the problem. It's actually the solenoid that does that sometimes.

Testing the starter electrical circuits should be done , not guessing as to what the problem is . Using wiring diagrams an a DVOM - digital volt ohmmeter .

Starter Voltage Drop

I owned a 95 SC1 manual many years ago. It acted like that for me, and stalled on a regular basis. Turned out the EGR valve was bad. I replaced it and all those problems went away. I'm not sure how to test it, but two bolts and you can pull the valve and make sure it's not crudded up. Don't use solvents or you can damage the diaphragm in there, just use a toothbrush and some rags. You should also use a new gasket when you reinstall it, although as a test you can reuse the old one if it's not damaged. While you do that check for obvious intake and vacuum leaks. There may even be a vacuum line going to the EGR valve. Hope that helps.

check fuses check relay inspect test wires going to fan for power if both check out good replace fan

check the crank shaft sensor its behind the starter they r cheap

97 saturn turn over wont start , getting fuel ; no spark

make sure ign module bolts ar tight and module is making good contact with trans case, if all is good you probebly have a bad crankshaft position sensor causing no spark.

have a 97 sl1 which was very hard to start and when it would it ran rough and stalled out easily. sometimes no start. It turned out to be the heater sensor on the engine block (right side as you face the hood. just under the heater hose. the part was 17.00 or 27.00
I don't remember which but it ultimately was sending misinformation to the computer module and it always "thought" it was too hot and would adjust incorrectly. the major clue was therm
indicator read hot even when cold and just started. took me 2 days
to figure it out before spending money. good luck.
