Default 1998 crank no start

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

if you're still trying to use that new key, it needs to be programmed first otherwise your car will not start.

previous owner doesn't sound like the sharpest tool in the shed.

You should check for power steering leaks, as that's what most likely killed the alternator in the first place.

Fix leaks, replace alternator
