Get a spark tester. It looks like a spark plug with a clip on the side (get the one that looks like a spark plug not the cheap plastic adjustable one if possible you will now what I mean when you see it). Unplug the coil wire and put the clip on your coil terminal and plug the coil wire on the spark tester like you would a spark plug wire. So that the spark tester is inline between the coil and the coil wire. While your at it get a noid light too. If you are not familiar with what a noid light is is plugs into the harness connector that plugs onto the injector. You can buy both of these tools at any auto parts store for probably twenty bucks or less. Then try to start the car until it does not want to start. You will know right away when you are trying to start it if it has spark because you will hear the spark tester snapping. If you have spark and it wont start quickly unhook a injector harness from a injector and plug in the noid light and crank it over. It should flash when cranking. This will allow you to figure out weather it is a injector pulse, spark or both problem. I dont have Accell system I use Holley, FAST and GM stuff on my cars. Does the Accell system use the OPTI for a crank signal or do you have a crank trigger?
Edit I just re read your posts so I know know it has a crank trigger. So See if one of the above is acting up (no injector pulse or no spark). Could be alot of things but we can figure out alot from knowing the results of the above tests. IE if its just no injector pulse or just no spark could be some things. IF it does not have spark and injector pulse it narrows it down some. Let me know what you come up with and I would be happy to try and help.
