I have the code P0193 on my escape. I know that the fuel pressure sensor could be the problem, but I should test the fuel pressure first as a process of elimination. I believe the car is a 4 cylinder not hybrid. Where is the port to test for fuel pressure, and if there isn't one how would I go about testing to see if the sensor is bad. I do not own a scan tool that could test it, and what should be the fuel pressure if there is a port. Thanks
