Have a 1995 saturn sl engine spins but seems to have no fire even with starting fluid can anyone help?

Assuming it is an automatic transmission, I would look into that first. Check the fluid level. Low fluid level will cause hesitation. If your fluid level is ok consider changing the transmission fluid and transmission filter. Saturn's have an external filter, so it's very easy to do.

The firing order is 4 1 2 3 it's from left to right looking at the ignition coil

If the engine fires up for a second or two with starting fluid then the fuel pump is weak.I would check the fuel pressure and if its not within the specs then replace the pump and filter.

Engines need three things to run, spark, fuel, compression, all at the right time. If your fuel pressure is good and you have spark then that leaves compression. Before you bother with a compression test first try to spray starter fluid in the intake to see if it will start on that. If it starts, it will die after it burns the fluid but at least you'll know the engine is good and you have a fuel delivery issue. If it won't start on the fluid then you need to do a compression test. You can get a compression tester from any auto parts store (I think even Wal-mart sells them) and follow the directions on the tester to do the test. Write down the results and post them here.

check fuel pressure and injector pulse...if everything is working than check the timing and the firing order...if it good than check the engine compression....

Have you resistance checked the injectors. If the resistance is wrong the pcm will shut the injector drivers down.

check out tips on saturn s series-i posted one which addresses your concern in grave detail

yes you do it is a spin on filter. Spin it on and replace with new one do not forget to check fluid level

mostly your thermostat . how is your engine heat ?

My manual shows----- code 22 is throttle position sensor, and code 83 is low engine coolant.
