Did you ever varify wheather or not the security light was flashing? It super simple to check and rule out as a possibility. if the pass lock sensor fails you will still get spark, but it will cut power to your injectors. So it will still run on starting fluid. you mentioned replacing the ignition, so that what leads me to believe its related to your issue.

Also the pass lock wire is the yellow wire that ties into the ignition, if it didnt get hooked up with the new ignition then it wont start.
