Mazda mx 3 1992 not start

Make sure the distributor cap and ignition wires are on correctly .If there're not it will not start.

NE1 SENSOR

Start by cleaning the fuel tank (water from condensation accumulates in it), clean the fuel lines, clean and adjust the carburettor, drain the old oil, remove the sparkplugs,put some fine oil in the cylinders and crank the engine manually, put new oil,oil filter,sparkplugs,distributor cap and air filter, replace the water and start the engine. Check for leaks, run the engine for an hour followed by an oil engine cleaner.

ignition coil may be defective

You need to get the timing checked, did you mark the position of the distributor before you took it off. If not you might be slightly off with the new distrib.

I think the seal around the distributor shaft is the primary problem. The oil is definitely causing the engine performance issues.

VSS or vehicle speed sensor aka cam sensor or crank position sensor. Test the battery and alternator. You should also check for blown fuses, bad wires and grounds on a car as old as yours. If you find it's getting spark and fuel after further testing, check the timing belt. It could have slipped or broke even if it was changed recently so either pull off the cover or at least do a compression test.

replace the oil cap and try again you may have to hold it to the floor the first time untill it starts

I am having a similar problem and my mechanic thinks it's a fuel regulator. Part was ordered and it's being replaced this week. We'll see. Unrelated, I'm/we're having a heck of a time finding an oil pan...mine is very blistered....but it is 17 years old.

as long as you are getting a signal to the injectors for them to inject, and you are getting fuel from the fuel pump.... I would check fuel regulator. I am assuming you are getting spark to the plugs.
