crankshaft sensor.

If the engine does not crank, the problem could be the security system, the key switch, the neutral safety switch, or the connections.

It won't be cheap. The rusted panels have to be cut out and new sheet metal welded in place. Most people just live with it.

pull the plastic door/floor trim driver side front. find the ground plate. it will be like a metal plate plugged into what looks like a diagnostic port, about 3 inches long and thin. pull this plate out. (it may take some doing. wiggle it with a pair of needle nose pliers til it comes out) you will see it looks like multiple blade connectors. clean it and the wiring harness you took it out of with contact cleaner and brillo pad. re install. these are bad for getting corroded from people leaving window down. once corroded they will heat up, and act almost like a breaker. when you use your window, they heat even more and lose ground, your fuel pump is on this ground as well as power seats and windows (dont know why). I hope this saves you alot of money and hassle that I went thru replacing fuel pumps and relays, before I got desperate and started tracing wires bumper to bumper. pass on the goodwill. goodluck.

sound like crankshaft sensor.

may be you should make a diagnostic and you can do it in a garage or you can do it by yourself if you want to do it by yourself you need some tools and you can find some good ones here: spobd2.com

If t dies hard - feeling like the trani is not disigaging when you stop - it could be a electronic part inside the trani.. This part tells the stall converter to kick in at a stop.. Not super expensive to fix.. But best done by a trani shop....

Locate the upper radiator hose. Follow it to the engine. The housing that the hose goes into is where the thermostat is located. The housing should have 2 or 3 bolts. Pay attention to how the old thermostat is positioned when you take it out. Hope this helps.

Without hearing the sound it makes - it's kind of hard to diagnose. The engine starting process consists of turning the key to start, the starter motor's rotor moving forward to engage the engine's flywheel, and then the starter motor 's "rotor" spinning until you move the key from "start" to "run". You can hear the starter motor spinning - but one usually can't hear the rotor moving forward to engage the flywheel. As a result, you hear the odd spinning sound - which is the starter rotor spinning. The engine never actually turns over because the rotor never engages the fly wheel. If this is the case, then it is very likely that your starter needs to be checked and / or replaced.Good luck!
