hey bro don't Triple post a topic
things you need to check:
-spark plug ( remove an single spark plug lay across valve cover and have someone crank your motor. and verify that there is no spark
( either one of these things will ruin your day)
-CAS( crank angle sensor)
-Igniter
-Connections
-grounds
check in that order, you should also run an diagnostic test, your ecu will tell you whats wrong.... unfortunately when you have a spark issue, it doesnt help if you cant get the replacement parts. remember these motors are not brand new, so don't be surprise if one of those parts fail..... give that a try and tell us what happens.

cool now you have to check your igniter and cas... only thing i could suggest is find a buddy who has a working cas and igniter and swap one at a time and then both and see what happens... spark issues are pretty simple to find unless something has gone very bad such as severed wire somewhere that you cant see.

man now it sounds like and electrical issue.... i would seriously trace you wiring. you could have a bad electrical load somewhere. check you battery terminals and fuses bro.. something is frying your ecu.
did you wire your car, or did some one else? if someone else, they need to check the wiring. SR wire jobs are simple to me, but they can be easily screwed up... also vibration can make wiring come loose if not done properly.
