2000 LHS ignition/start issue
 

After changing my alternator, starter, battery I was still getting a tick, tick, tick then my car would start , sometimes slow as if battery was low n sometimes normal. It was doing that b4 I changed all 3 things I just mentioned. Then for 3 weeks it was starting with no problem. I noticed when I take the key out and my seat goes back it was starting normal. But when the seat doesn't go back and I have to turn the key on then off twice the seat will go back this is when I have the starting up issue. It's always been normal for the seat to do this when you turn the key on or off. The seat goes forward when turning car on then back when turn car off. the abs & track light come on after the car goes over 10mph but I heard that has something to do with the back brakes? I read something about the security system also. I noticed when I turn key back n forth to off to get seat to go back the red security light stays constant on red until I get out of car and lock doors with remote. Car was my dad's before he gave it to me. has 284k miles and has been a great car.
