I would refer you to some previous posts of mine, but with this new "improved" list software, I can't get back there to section VII or VIII, where ever it was to find the reference.
I and at least one other LS owner had a problem with the PATS (Passive Anti Theft System) that caused a no-crank situation. If you are experiencing a no-crank condition, watch the PATS LED on the top of the dashboard after you turn the key. In my case, it began to flash rapidly; then after about a minute it stopped for a few seconds and then flashed once and paused and flashed once again, to indicate the code "11" (as I recall).
In my case, the problem was a bad connection between the four-conductor cable to the PATS transceiver and its connector. This is right next to the ignition key lock. I pried the small simulated wood plate around the ignition key lock off and could see the cable and connector with a green part on it. I took a pair of needle nose pliers and firmly grabbed the cable and vigorously tugged back and forth on it to better seat its connection with the connector. The connector makes contact by puncturing the insulation in the cable when a machine squeezes it down onto the cable during manufacturing. If it isn't squeezed down with enough pressure, the little contacts don't make a good connection, and if the insulation expands a little, it will open up and you won't be able to start your car. After I reseated it (probably last August or September) it has never failed again.
