My '90 Mustang w/ a 4 cyl. has a problem. When I turn off my car, the fuel system keeps running. The fuel pump doesnt turn off and listening under the hood you can hear it in the fuel rails cycling gas. This ultimatly leads to a dead battery and probably will get into worse condition. So is this a fuel pump relay or fuel pressure regulator problem? Any help will be greatly apprieciated.
