sons del sol is a 1993 SI.mostly stock.starts hard in the morning or when its been sitting for a few hours.it will crank for about 15 seconds then finally start and run fine.if shut off it will start up right away as it should.im thinking its a fuel pressure issue,but the car has a new ECU,main relay and bosch fuel pump...still no joy.what else can cause this?it does run like a champ when it finally starts,and if you turn the key to the run position and let it sit 4 or 5 seconds the check engine light goes out,fuel pump primes and it starts as it should.any ideas?
