hi everyone i have an issue with my 20b with hot start.
my car wont start when is hot.I changed the starter to 2K high crank starter.also change my battery is PHCA-2150, CCA 1150, AH-100.
is still wont start.can anyone help.

 

Have you checked fuel pressure. Pumps can drop pressure when hot

 

 

All my hot start problems were related to internal coolant leaks from my PP modification. You're not dropping coolant levels are you? Also, how low is your voltage dropping while cranking hot? Depending on your coils, sometimes cranking volts drop low enough that the coils don't fire properly.
