thank's a lot, but its not vapor lock becuase if i let the car sit overnight, it will not start up unless i "prime" it without cranking it. However, it starts up without a problem 15 minutes after driving 30 miles at 60 mph (which i did today). So its not vapor lock, it has to be the pump check valve or an injector not holding pressure. Any way to narow it down between those two?
