You could have a weak fuel pump. Best thing to do is check your fuel pressure, it should be 40p.s.i. Also your fuel regulator could be letting fuel back to the tank and you have to let it build up pressure before it starts. A pro can check these things out for you. Also have the engine scanned for codes as well.well first we need to verify which component we are missing when this no'start occurs, here is some info on how to check this
