Hello, working on a 1993 Maxda 323. Cannot find a code reader for this OBD1? System. I have a no start condition. I have spark, I have fuel delivery to the rail, I have power to the injectors. Suspect a cam sensor or ignition mod but cannot find a component locator chart. Any ideas? Thanks for any response.

Thanks for the response rasmataz,

I have checked the timing belt and it is ok. I have compression and fuel and spark. I will bring no1 to top dead center and check the rotor for alignment to #1 spark plug lead. This is really a perplexing problem. Spark, fuel, compression. Darn thing should run but just cranks over with no indication of wanting to fire up.

Is this a carb or an EFI system-if its an EFI could be the injector/s are not pulsing. Try getting the valve and ignition timing straight. Have you attempt to check fuel pressure? If not do so.

I checked the timing, No #1 cylinder TDC - rotor aligned to #1 ignition lead.

Parts swapping time, hate to try and fix cars this way but with spark, fuel and compression I suspected the ignition module located in the base of the disributor was nfg. This mod appears to funtion like a cam sensor, this early version of the 323 does not appear to have a crank angle sensor or knock sensor. The ECU seems to control the spark timing via the ignition module. Anyhow I replaced the distributor as the module is stated as unserviceable, and the engine fired up instantly. So the Mazda 323 can have spark, fuel and compression and still suffer a no start condition. The older versions ( Like this one - 1993 ) of the real time emission control vehicles, even with minimal sensors, are a pain to trouble shoot without the factory manual and a scan tool. Although in this case, as the failed distributor did not set a fault code. No ( service engine soon light ) reading the codes would not have helped.

I Still have not found any manufacturer building a OBD1 tool for this model. Perhaps the factory manual explains how to decipher the codes via a blinking dash board light. LOL

Thanks again for your assistance.

PS The above motor is the 4 cylinder 97.5 CID / SOHV with multi port EFI. The engine family is
RTK1.6V7GAEA
