I installed this pump (3s4z-9h307-ba) And it ideas at 35-40 psi, But as soon as you put it under a load it falls on it's face and drops to 5 psi and never comes up again untill you turn the car off and start it back up. Has anyone had this problem with this pump? Please help if you have an suggestions.
