Fuel Pressure

Hi All,

I have a 1998 Ford Contour with the 2.0 engine and when I shut the engine off, the fuel pressure quickly drops to zero. I have 32 psi running and 40 with vacuum disconnected. I read where it should maintain a pressure of 26 psi for 5 min. after shutting the engine off.

Do I have a bad fuel pump (check valve?), pressure regulator, injectors leaking into cylinder (is this possible?) or something else? There are no external signs of leaking.

Thanks,
Greg Smith

Re: Fuel Pressure

How did you come to be checking the fuel pressure?

Re: Fuel Pressure

if u pull the return line off the pressure regulator and ints wet then the diaphram in it is bad, otherwise if not id start with a new pump moe than likely. if ur injectors were leaking that bad it would prolly have a hell of a time startin.
