I recently purchased a 2001 mustang as a project car and have gotten it to the point to try and start it, it will crank but wont start. After doing some troubleshooting I have determined that I have zero fuel pressure at the fuel rail. I have tested power go to and from the inertial fuel switch and I have getting 12v in and out leading me to believe it is the fuel pump that is bad. Anything else I should check prior to dropping the tank and replacing the fuel pump?
