I have a 2011 escape with 40k miles. It has a problem starting. The engine will cranks for a long time before starting. I found that if I turn the key from off to on a few times the car will start right up. I disconnected the fuel line and connected a gauge on the line from the tank. I turned the key and noticed the pressure went to 10psi. The pressure then slowly went to 0psi. Turning the key multiple times increases the pressure by 10psi every key cycle. My scan tool can not read the pressure sensor. Does anybody know what might cause me this and what I can do to further narrow down the problem? Is 10psi too low? How long should it take for the pressure to bleed off? Thanks in advance.
