So I have a 99 2.2L s10 and something happened today where it would start fine and whatnot. But randomly the security light comes on solid not flashing. And if I shut the engine off it varries on wether it will restart or not but light goes off usually fairly quick on a restart.

So whats the issue with it, ignition switch works fine.? No codes even when the light was on.
