If we have an ignition spark at the plugs and fuel (starting fluid) and it doesn't at least try to start, we have something different going on.
To answer your question, yes, a security system could prevent it from starting. Is it a factory system or is it an aftermarket system?
Also, you have me concerned about having spark but no change when using starting fluid. Is it possible for you to record it cranking and upload it for me to hear? If it has spark and fuel, it should at least try to start unless there is a compression issue or ignition timing. If I could hear it cranking, I should be able to tell if one or the other is a possibility.
Let me know.
