1991 ford mustang start but no start condition?

[Eric W]

The vehicle starts up fine with the engine cold. After it warms up to operating tempature, took for a short drive and the engine stalled out. Tryed to restart and it will not crank or will barely crank over. The battery has plenty of power and was also hooked up to another car for extra boost and still very slow crank if any. The motor is a 351 cleveland. Anyone have any idea's? I'm completely and utterly stumped beyond belief!
the starter is brand new. We replaced that and the flywheel so that starting would be no problem. When it starts up at first, when engine is cold, its very quick, BUT when it heated up, the starter seems to barely crank over the engine at all. The timing hasn't moved since its been started but not driven a few times and the distributor is brand new also. SO I should look into the timing?
the starter wasn't very hot after repeated attempts to start the car in 40degree weather. It is a brand new starter but I will definitly check and spray water on it, however the starter solenoid is built into the same chasis as the gearing. If you go to any local auto zone or in our area, we have a place called JK auto parts that we were able to get a new starter from. As far as the exhaust is comcerned, that is fine, no leaks, headers are from summit racing and the engine has never had a starting problem from them before. or from the stock manifolds. So far it sounds like check timing, wiring and starter to make sure operation is exact?

It could be a matter of the starter getting too hot. You say it has a Cleveland in it, so it's had a engine swap, and I'm thinking you have headers on it. I had a similar situation with my '70 Mustang with a 351 Windsor in it. There was an exhaust leak that was letting some of the hot exhaust gasses hit the starter motor, so when I would try to start after shutting it off, it would be very slow to crank, or not at all. Fixed the exhaust leak, and problem fixed. In your situation, check to ensure no exhaust leaks are near the starter motor or that you have the header pipe running too close to starter. You could try to fabricate a head shield for the starter to deflect the heat, or use a heat shield wrap (available from places like Summit or Jeg's) and that should help.

underneath the hood threes a clicking sound on a thing called the solenoid... the points on this will need cleaning... sometimes its a separate item.. and sometimes its part of the starter motor.. listen for the click under the hood [ bonnet. uk. ]... there are a set of points in that bit.. take the cover off. and clean up with a fine abrasive then make clean with rag.. then try again to start..
but remember... when messin' with electrics on vehicles.. dissconnect the earth cable on the battery to avoid sparks or fire...
