I had just bought a 98 ls 2wd..At first I left some interor light on and ran the battery down.I jumped it off and went to autozone.They tested the alt and battery.They said both were fine.Last night I pulled up infront of the house.Pressed the dome over ride switch off to let the inside lights come on..Put a steering wheel cover on.Waited 5 min for gf to come out.When i turned the swith nothing.No clicking nothing just would not turn over.Tried jumping it off still would not turn over no noise nothing.This morning I checked the fuses on the driver side dash.All were good.I looked at the relay fuse box on the driver side under the hood.Only one that was blown was the trl trn fuse.????? I replaced the starter fuse still same problem.Also if I ever leave the interoir light on or anything on for a min or two.Its a little slow to start.So thats why I leave the dome over ride switch on.Also when I first bought it.The ses light came on.Went to autozone they said the codes ment it was running lean.Prob a vacum hose.So I looked and the pcv hose to the air filter box was unplugged.I plugged it in to the aif filter box.The light went off.Its been runing great but all of a sudden nothing?? Is it the starter or solenoid or wire/fuse some where....... I had no idea what that hose was until I looked it up on here a week ago .Only know the basics help

 

I would take the starter off and get it tested.
