Welcome to 2CarPros.
Does the starter still engage and turn the engine? Also, if it does and won't start with starting fluid, check to see if there is spark to the plugs. If there is, I have a feeling the head gasket went and you don't have enough compression for it to run. If it does turn and won't start with starting fluid, it isn't a fuel related issue.
Here is a link that shows how to check for spark:

Here are a few links you may find helpful when checking for spark and the wiring involved:

If the engine will not turn when you try starting it and the battery is good, there is a chance one of the cylinders has filled with coolant from a bad head gasket.

If you find there is spark, then you need to check engine compression to see if there is an issue with a head gasket or warped head. Here are general directions for testing compression. You will need a compression gauge, but most parts stores will lend or rent one to you.

Here are directions for testing compression specific to your vehicle. The manufacturer's specs are included in the directions.
___________________________________
Perform the following steps in order to conduct a compression test for VIN 4:
1. Conduct the following steps in order to check cylinder compression:
1.1. Engine should be at room temperature.
1.2. Disconnect wiring from the ignition module.
1.3. Remove the spark plugs.
1.4. Throttle body valve should be wide open.
1.5. Battery should be at or near full charge.
2. For each cylinder, crank engine through four compression strokes.
3. The lowest reading cylinder should not be less than 70 percent of the highest.
4. No cylinder reading should be less than 689 kPa (100 psi).
Important: The results of a compression test will fall into the following categories:
Normal-Compression builds up quickly and evenly to specified compression on each cylinder.
Piston Rings-Compression low on first stroke. Tends to build up on following strokes but does not reach normal. Improves considerably with addition of oil.
Valves-Compression low on first stroke. Does not tend to build up on the following strokes. Does not improve much with addition of oil. Use approximately three squirts from a plunger-type oiler.
