I bought a 1998 ls400 last week that had been sitting a few months. The previous owner started to have the alternator replaced, a bolt was broken off in the block. I purchased the car was told it would run if the battery was charged. I came to get and put a battery in and it started right up I backed out to load it and shut it off. When it arrived home we rolled off of the flatbed and I started and moved in my driveway. 2 days later I cleaned the motor compartment and now it will turn over but not start. I have used start fluid with no change. I also tried to start with a new transponder key. Don’t think it was ever set up. So when cleaning out the trunk I found the timing belt tensioner opps. I installed and tried again no change but sounded a little different. I them pulled the inspection covers and the left can was off about 4 teeth. It is now back in time and sounds different but no start. I did pull a coil and put a plug in and had a weak spark. Does the security system kill all spark, part spark, fuel? I did try the 6 minutes in the on position any ideals. Thanks
