i have an 86 transam the car will start and run but once its warm and i shut it off it will not start untill it cools down whats causing this? some mechanics said it was the battery i replaced it and it still does it. also i noticed someone direct wired the positve cable from the battery to the altanator and a positve cable to the starter it has a top mount and side mount battery could this mean anything could the starter be bad?

As far as the wiring goes, it is normal to have a direct wire to the alternator and starter from the positive post. Probably just means someone changed the wires. But yes your starter could be bad but it might just be getting too hot from your exhaust. Is there headers on the car? If you have headers on it you need to have header wrap on them. This helps keep the temp down under the hood and looks cool too. it is also a good idea to wrap your exhaust pipe where it passes your starter to help keep it cool.
The other thing that could be wrong is your timing could be a little too far advanced and stopping the starter from turning the motor over fast enough to start. Hope I have been helpful

Sounds like an electrical/starter problem. Not sure what the wiring actually looks like, but the main positive battery cable needs to attach to the starter, not the alternator, but there is usually a smaller wire going to the alternator from the battery. Odds are, the starter may be getting old and weak, or it could be just an old, corroded battery cable. When electrical wires get hot, they don't work as well. They are fairly cheap to replace. Check and make sure all electrical connections are clean and tight. If the car has headers, the exhaust heat really kills a starter motor. If it was my car, I'd just go ahead and replace the starter and the main cable, just to be sure. Doesn't hurt to check/replace the ground cable also.

Is the car fuel injected or carburated?

What you need to do is figure out when it won't start if it's not getting fuel or spark... So next time when it dies remove a spark plug/wire and hold it to the block (or any ground), crank it over and see if you see a spark...

You really would be better off asking this quesion on the transam forums where people have specific knowledge of your car and normal problems... If you don't know where one is search for "trans am forums" or "transam forums"...

Good luck!

I would try putting a heat shield around your starter. Put it between the starter and your exauhst manifold and see if that helps. It doesn't necissarly mean that your starter is bad. But in my experience I have seen vehicles not start before because thier starter bendix had got overheated. Just try making your own out of a piece of aluminum. It works best because it dissapates heat better.

most likely a module under the coil packs or a fuel pump.after car is hot and problem happens dump cold water over the coil packs to cool them and the module.if it starts wala.if not go to the fuel pump which is not easy to check.before starting car when cold,take off gas cap,put ear close to filler hole,have someone else turn key to run position and listen for pump to kick on.remember this sound.when car apes up do this again and listen for pump to make same sound.if no sound or one that is very different its could be a bad pump.
