Turns over but no start....
 

I'm having an issue with my 91 Mazda 323 and I can't seem to get it to start. I bought it from someone who changed Wires, Spark Plugs, Fuel Pump and Fuel Pump Relay yet still the issue presists. The only thing I can think of next would be to replace the distributor or see if maybe it's off at all? Anyone have any suggestions that I should check or try? I'm new to 323's as I have just bought this one and am trying to bring it back to life. Would love to get this 119k miles beauty back on the road where it belongs. 😋

I'm assuming you've checked the battery voltage...
Can you say more about the symptom? Does it sound like a strong turn-over?
Have you verified you're getting spark when it turns over? Have you verified the fuel is pumping to the engine when you turn the key on?
The distributor is a good place to check. Do you know how to inspect the distributor or make sure the plugs are connected properly?
There are a lot of potential causes. For example, your cam timing could be off as well. You can keep throwing parts at it since it probably doesn't hurt to have new wires, plugs, fuel pump... but I find it best to take a systematic approach. First verify you have spark, fuel and air and then take it from there.
