just so you know there is a check valve (of some sort) in the fuel system,, if everything is good and working,,,turn the key the car starts,,,but if the check valve has stuck open,the fuel drains back into the tank, and for the car to start it needs fuel, to test this turn your key on (not into start) wait --count to 10, turn off the key,,, repete,, turn the key on (not start) wait then off,,,, then start the car normal, if the car starts within 3 cranks that is it.,
