97 Saturn wont start, turns over has spark and fuel pump is working

Are injectors firing? Does it do anything or just spin over?

You can use a noid light. or make your own. http://www.noidlight.com/making-your-own-noid-light/

Just to add to this one sounds like a bad coolant temp sensor. Try holding the gas pedal to the floor while trying to start it see if it starts?

I really doubt you lost injector pluse on that car. The injector harness runs across the back of the valve cover unplug the injector plug the tester in crank the engine the light should flash and not stay on solid.

You should have checked all four injector pluses what is your actual fuel pressure you have?The coolant temp sensor is screwed into the right bellow where the upper radiator hose goes on. It has a black wire and yellow going to it unplug it and see if the terminals inside the connector are blue or green instead of silver. You need a multimeter to test it.

You would rent a fuel pressure gauge from auto zone and I could give you more info when you get one. You need to check the resistance of the sensor and know me know what the outside temp was when you tested it. The sensors are only like 10 and they have a high failure rate.

Checking resistance would all depend on the meter usually the meter leads would be in the same place plugged into the meter as checking voltage. Then you would set the ohms meter to ohms scale 2k. Then measure the resistance across the two terminals of the coolant temp sensor. As far as checking fuel pressure remove the air inlet tube. Then on the fuel line running up to the fuel injector rail you will see a threaded fitting on the hose. Screw the fuel pressure tester on there then face the pressure tester so you can read it while your sitting in the drivers seat. Then crank the engine like you trying to start it you see 40-50psi fuel pressure. It will most likely bleed down on that car the fuel pumps had a lot of problems on the 1997 saturns with that. But see what the fuel pressure reads before it bleeds down.

For that temp the chart says 5,670 ohms.

We need to check the actual fuel pressure. Also try turning the key to the run position leave it there like two seconds then repeat 3 times and see if it starts.
