Hyundai Repair: 91 Hyundai- repair ideas, hyundai repair, power transistor

Question
I know little about cars, but i am learning.  I have a 91 Hyundai that has been sitting for about 8 years and I have just decided to fix it (on my own).

The car seems to be turning over very well, but it isn't starting. i have made sure that the distributer is working fine, but there is still no spark to the spark plugs (two of the four were tested). The battery was replaced becasue it was weak, and it helped the car turn over better....but it still isn't running.

I am a novice, so I am not sure what avenues to pursue with this. Ideas?

Answer
This car has a single coil and distributor, so it's possible the problem could be with the power transistor (similar to ignitor), the ignition coil, the distributor, timing belt, or the ECM.  To provide spark, the sensors in the distributor give a signal to the ECM of the engine position.  With this information, the ECM sends a signal to the power transistor, which then fires the coil, and the spark travels through the coil wire to the distributor to the plugs.

Since the car has been sitting for 8 years, I'd recommend by checking the timing belt and cam timing.  It's possible the timing belt stripped just from age.

After that, my next guess would be the coil, but you're entering a situation where this is a low enough percentage guess that I don't recommend trying to repair by trial and error.  

One other check you can perform is to observe whether the check engine lamp comes on for five seconds when you turn the ignition key to the on position.  If not, you have a problem with the ECM or its power or ground.  If it does illuminate, then the ECM is probably (but not definitely) okay.
