[cleancoupe]

i have a 1990 240 coupe, ka24e the car runs good and starts prefectly fine when the motor is cold but if i drive the car for like 30 min or more then park it and go into a store and come out 20 min later car wont start, if i pull over to just get gas (5 min) it will start fine. ive replaced coolant temp sensor coolant temp sensor pigtail connector off harness, all 4 fuel injectors, fuel filter, spark plugs, and gutted my cat due to bogging issue but still have no start problem. please help i am getting highly frustrated. thanks

Its most likely your coil....When they heat up they usually wont start till they cool down.

Intermittent is usually the starter solenoid....
