Ok, I have another question maybe somebody can answer for me, my GTO probably has run maybe only a few hours since it was overhauled total. It has a new starter/battery ect... When the engine is cold, it turns over easily and fires right up. After the engine is well warmed up, if I shut it down then try to restart it after 5 minutes or so it wont turn over hardly. After it cools off, it turns over fine and fires right up again. Its like the starter has a hard time turning the engine over after its warmed up. Im pretty sure the problem isnt with the starter, I had the battery and the alternator checked, no problem. Not a fuel or spark problem. All I can think of is that when its warmed up the tolerances are less and that makes it harder to turn over. Has this ever happened to anybody? Thanks in advance.
