Under the hood there is a diagnostic check connector box as I recall is on the driver side just behind the strut tower or back by the firewall and brake booster. It is approximately 2" x 1" and deleted will unsnapped and in identifications are located inside the lid. If you place a jumper wire in TE1 and E1 then turned the ignition switch to the on position and monitor the check engine light it will flash a series of codes. For example if you have a code 12 the check engine light will flash one time then a slight pause than two flashes. If there is a additional code it will follow then the system will pause for 3 seconds and repeat itself. Let me know if you can get any codes from the system. If the check engine light is flashing steady and consistent this means there are no codes set. Checking for codes is always the first place to start to help narrow down what could potentially have gone wrong.
With the ignition key in the on position is the check engine light illuminated? Have you actually checked for spark at the end of the spark plug wires while cranking the engine over?Skyvisions
The most common problem is usually related ignition coil. When one day it starts and no start condition occurs the next day usually the ignition coil fails. You said that you had the integrated ignition coil inside the distributor. Remove the distributer cap inspect it for any cracks or discoloration on the side of the ignition coil. Click the link below for a better view and description of what this may look like. This is a very common failure. If you're certain that the fuses are good and you have power to the positive side of the distributor or positive post of the ignition coil and everything else checks good this is the most common denominator.
