No. I don't think that disconnecting it again would be any different from the last time. The security light should go out a couple of seconds after the key is turned to the ON position. It should be steady, not flashing. Is that the case?
Also, check for a spark at the spark plugs, when cranking the engine(if you haven't already).
How to check for a spark DIS system
1. Disconnect a spark plug wire at the spark plug end.
2. Connect the plug wire to the spark tester and ground the tester to an appropriate location on the engine. (If you don t have a spark tester, put a screwdriver into the spark plug end of the wire and lay it on the engine so that there is at least a inch gap between the metal part of the screwdriver and a metal part of the engine)
3. Crank the engine and check for the presence of spark, and also the intensity at the tester. (Or a spark between the screwdriver [metal part] and the engine)
4. If spark exists at the tester (or screwdriver), the ignition system is functioning properly.
5. Repeat the procedure on at least one of the remaining spark plug wires.
