My car has an automatic transmission.
Hi there. Your Fusion can be stalling for any number of reasons. If the fuel system is producing as much pressure as you are stating then the fuel system should be fine. It sounds like you may have an issue with the crank position sensor or it may be an issue with the idle control valve. If the engine stalls only at idle or low speeds then I would suspect the idle control valve. If it stalls at all speeds then it may be the crank sensor or one of the main relays. I usually check the inputs from the sensors when the engine starts to stall to see where the issue is.
