i have a 91 mustang gt it start great cold but after you drive it and it warms up if you shut it off it wont restart.it runs great but will not restart. i have put a new tps on it o2s mass air flow. it is a 306 has e303cam cold air intake 65mm tb headers h pipe flowmasters anything will help thanks

try cutting your timing back a little bit. Did you screw with it lately or is the bolt on the hold down loose?

Is the hot restart a cranking problem or is it cranking just like cold but no fire?

yea i have the timing set a 14 the hold down is tight. it start great till it gets hot then you shut it off and it will crank but wont fire up. if you let is sit for around 30 min it will start back up

it will crank till the battery dies but wont ever start back up till is sits for a while

need a new tfi module

+1 they are about 40$ and youll need a tfi screw drive to remove it thats about 5$
