Question about 1993 Ford Ranger SuperCab
Engine cut off and would not crank, pulled plugs and found all cylinders full of fuel. Pulled upper intake and found it full of fuel as well.
Sounds like the fuel pressure regulator diaphragm has ruptured. When this happens fuel is drawn in from the manifold vacuum and if the leak is severe enough the fuel pump pressure will push it in as well. The unit is a small component that resides on the fuel injector rail and will have a vacuum hose running to it. Remember you are working with GASOLINE and lots of it so be careful!
