    Won't Start After Driving

    I have an annoying problem that I'd like to get fixed but I don't have a clue where to start. I have an '89 seville with a 4.5L engine. When I drive home in traffic the engine temp will get up to about 226 then drops down to to around 210 when the fan kicks on. When I get home and can shut the engine off and then restart it with no problem But if I let it sit for 10 minutes the temperature on the display will go up to say 235 and then I cannot start the car until the temperature drops back to around 215. When I turn the key the light etc come on but the starter does not attemp to engage or turn over. The car does not act like its overheating. An hour later it starts fine. I'm thinking there mus be a temperature sensor kill switch. Any ideas?

    Typical "no start when hot" condition. If you cool down the starter somehow (with water) it will start. The armature(rotor) inside the starter went south. You have to replace the starter, which is not very hard. Search the archives for hints.
