I have a 92' Mazda mx3. It will turn over with no problem but the engine wont start. Tried spraying starter fluid in the air intake and it didn't help with anything. Would it more likely be fuel related or ignition related?

If you need to use starter fluid you need to get the engine checked by a good mechanic. When was it last given a full service?
You'll need to remove the air filter and spray it directly into the air intake. Starter fluid is nasty stuff! If you get it on the air filter and you get a flame blowback from the air intake it'll burst into flames like a flare!
Starter fluid is only meant to be used once or twice like in an emergency or starting a petrol engine after a very long time in storage.

no
you fix the reason why the injectors are not working
could be fuel pump , pressure regulator , injectors , wiring or ECM
have the fault codes read

remove the air intake snorkel from the air filter to the engine and spray into the intake of the engine, while someone is trying to start the car.

Try spraying starting fluid into the intake. Remove the air filter to do this. If it starts for a few seconds then you have a fuel delivery problem. If it does not, then you have an electrical problem with the ignition. there are 3 things needed for an engine to run if it turns over. Air, Gas, Spark (fire). No air filter solved the easy air issue. Add starting fluid answers the fuel issue. Only leaves spark after that.

The easiest way to rule out a fuel starvation problem is to remove the rubber air tube between the throttle body and the air box, manually open the throttle body valve and spray a short burst of stating fluid into it. Quickly release the valve, and attempt to start the car. If it starts and runs briefly then you are not getting fuel.

one answer is lack of compression in the cylinders,normally associated with high miles.
could also be valve seats/spark plug gap/dirty air filter,there are a few more but start with the cheapest to diagnose and work up.....

it sounds like a starter, you can try hitting it and it shud work but you would have to get it replaced , also check to make sure the belts are tight

Check your fuel filter, fuel regulator, and fuel pump. It sounds like you are starving the engine of fuel.

how many miles are on it try starting fluid in intake if it hits its fuel if not it is probally a timming belt

here is what you need to do, a cleaning of the intake throttle blade and the idle speed control air-bypass valve, they get full of gunk over the miles and cause idle issues (stalls) like yours,
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
