I spent much of Sunday watching the rain fall and typing up the pinpoint charts for a DIS no start condition. I picked that one because there are some good diagrams with it as well as coverage on some testing of the failure conditions of the Crank Sensor, the DIS and the Coil Pack. The Cam sensor isn't covered because the CAM sensor isn't required for the engine to start. But the Crank Sensor, DIS and Coil Pack are required.
Note for most tests on the DIS you need to use a LED tester, not a 12volt test lamp. This is because the 12volt test lamp can create a load on the DIS system causing starting problems, or throwing off readings. Here is how you make a LED Tester:
A LED test lamp can be created with some simple parts from Radio Shack. You need 2 resistors, and one dual LED.
2 of the Radio Shack 271-019 470 ohm resistors.
1 of the Radio Shack 276-012 Red/Green LED.
Hook 1 lead of the LED to one resistor, hook the other lead to the other resistor. You now have two leads to test from. Power one way will turn the led red or green. You can use a 12v source to test and then label one lead - and one lead +. Thus you'll know which color lights up for power going which direction.
Below is the link to the pinpoint chart, I hope it becomes useful:
