My 1996 nissan 200sx won't start

If the starter fluid worked for a little and the engine died again, it may be some of your filters. Check the air and fuel filters and replace them if they are dirty or haven't been replaced in a long while. This is the most common reason a car won't start.

Another idea is the engine may have been flooded. If you have a fuel injected engine, don't pump the fuel when trying to start it. The fuel pump primes the engine all on it's own. If the engine is already flooded, push the fuel pedal all the way to the floor and hold it there while you try to start the engine. This bypasses the priming and opens the air to blast any unburned fuel out of the cylinders.

Check to make sure you are getting spark with an inline spark tester (at auto parts stores) and if not try replacing (in order) the spark plugs, wires and (depending on your engine) the magneto's or distributor cap. Ask the auto parts store if they can look up if you have a distributor-less ignition or if you have a distributor.

So, first the filters (air and any fuel [there may be more than 1]) then check for spark and replace the spark plugs, wires, and magneto/distributor cap.

I hope this helps and good luck! Don't forget to rate! Thank you!
