Security Light

Could be the start of your ignition switch going bad. My symptoms started with the security light/no start situation then turn signals and gauges started wigging out. Only had to replace the switch itself, I was able to reuse the key cylinder.

It's likely you only need to replace the ignition switch itself and can reuse your old key cylinder. I think the switch was may 40 or so.

Looks like you can use the same one as my 2001. Google Dorman 924-701
