1991 hyundai scoupe; engine cranks but does not
You stated the 'CHECK ENGINE' light came 'ON'!... what/which DTC'S (Diagnostic Trouble Codes) OBDI were retrieved? In 1991, OBDI (1) was used. You could retrieve codes by either turning the ignition switch on/off two or three time within 3 seconds and the light would flash for each number (this way you could determine which system was affected). The POSSIBLE CAUSES are many:
Crank Position Sensor
Electrical (Relay(s), fuse(s), Poor ground connections, failed ECU (Engine Control Unit), etc.
Are you getting a SPARK to the plugs?... if so, check fuel pump pressure
If you're not getting a spark to the plugs or not getting a fuel injector PULSE, then the crank position sensor MIGHT BE the problem.... NOT SURE!
Too many POSSIBLE or PROBABLE causes.
In order for an engine to RUN, it needs these things:
1. Air flow (intake AND exhaust)
2. Fuel (proper fuel to air mixture)
3. Compression (140 to 2?? psi)
4. Proper Timing (not too advanced/retarded)
5. Ignition (sufficient and at the correct/right time)
Now, after listing these 5 things, without CHECKING each one, your guess is a good as mine.

How do i fix a hyundai scoupe starting problem?
If you have a national auto parts chain store near you (autozone, advanced auto parts, pep boys,etc etc) Have them hook up an obd2 tester to your car and see if any codes come up(they do this for free!!!). If nothing then I would check the ignition switch module inside the steering column, it may be energizing the starter motor but not sending a signal to the ecu that the car is trying to be started.

Atos ignition problems and screeching
If you hear a click under the hood from the starter the starter solenoid but starter is defective and you should rebuild it. If that is not the case I would replace the ignition starter switch, this is the electrical switch the key cylinder actuates to turn on the electrical system and engage the starter.

2006 2.9 turbo diesel
dear friend-it is very difficult to explain myself in a text. I would say ignore the fault codes at hand for a while untill we have a definate fault. I would like you to make sure that the battery is fully charged, when you carry out the next exercise. I want you to try and start it with quick start, but please do not crank to long, gentle squirts will do it. If no joy, then we must go live chat- I am sure it will work, but please come back to me
