will it start right up after it dies? or do you have to wait awhile before it starts up again?
and what have you replaced already with the 500 dollars.
and with the several turn of the key. in the morning like the first time you start it for the day. put the key in the on position, don't crank it. you should hear the fuel pump prime. you will hear it whine. once it stops whining then try and crank it.
it could be that once your car has been off for a period of time. your pump can't hold pressure in the fuel lines any more and it drians all back into your tank. hence no fuel and no fuel pressure in the lines. a simple replacement can fix that.
