04 stratus won't start

Hope you figured this out. If not, this is how I do it.
1. Spray starter fluid into air intake. Starts up but dies? Fuel problem. Injectors, pump, lines, pressure regulator. Doesn't start? Spark. Coils, coil mount, plugs.
2. Compression. Engine turning over with low compression has a distinct sound. Could also do a compression test. Engine gaskets, seals. Last problem you want tbh
3. Air. Check for blocked passage ways. Throttle body opening. Hoses that are split. Air filter. You name it. Once my car wouldn't start because the butterfly valve wasn't opening when throttle was pressed.
And lastly (most difficult)
4. Electrical. Check your fuses and relays. Test your fuel pump relay. If you have a immobilizer check to make sure it's not cutting off fuel supply. RPM and Speed sensors. Any one of those bad will stop a car from running. Check for shorts. Test every sensor. Check for faults on OBD. If you have a scanner, make sure the car is picking up RPM readings while cranking the car.
In my experience with crank no start, it's been the fuel pump.
Just don't give up and keep trying. Took me two weeks stuck in a garage one time. (Fuel pump went, then butterfly valve wouldn't open) but I eventually figured it out. Best of luck.
