my 2000 hyundai elantra wont start it has almost 188,000 miles .... i've replaced the ignition module, all the spark plugs, air filter, fuel filter, fuel pump relay, fuel pump, and computer ... what else could it be... the car wants to start but just wont turn over ... anyone have any ideas???

 

It's too late now but just replacing parts without finding out what is the actual problem is very expensive and, as in your case, may not solve the problem.

Check the crank position sensor.
