Ok I thikn this will need a sticky. There are alot of question about this and I think that this would clear up alot of confusion and frustration.
Obd0 Ecu pinout



This is how the pins are counted. It is easy to see where they start on each one.

Now this is for the all mighty IGNITOR that everyone hates.
If you car suddenly dies do this. Its very helpful.
1. Ignition should be off. Unplug your dizzy. Then turn on the igniton. The plug with two wires is the one you will be testing. Take a multi-meter and check the Blk/ylw for voltage. With the ignition ON there should be battery voltage. If not there is a short some place.

2. If there is voltage and the car still doesn't start you will need to check the two white wires coming from the dizzy. To do this you will have to check them at the ECU. With the iginion on and the ecu still plugged in, you will have to stick the multi-meter in pins B15(+) and B17(+), they are right next to each other, with the ground at A18(-) you should get +/- 10V. If you don't have voltage, it's the ignitor.

If it happens to be the ignitor then you can just buy that part at the store. But they don't call it the ignitor they call it the Ignition Control Modual. It was $60 for mine. Better than a $180 dizzy with core. They happen to be the same as obd0 and 0bd1 cars. I don't know about obd2. Haven't tried it yet. good luck

I will post more up as soon as I figure somethings out.
