The tank has been off to see if there was any restriction and there is not a fuel pump located in the tank. There is a solenoid on the pump and this is the inlet metering valve, there is only a pressure sensing device on the rail.

I think I stated in the first part of my post but here we go. I get called in when the obvious, in most cases has not been successful. I can see serial data to the inlet metering valve of 16-30%, 1v - 2v if i scope the rail pressure sensor dependent on throttle position command, some times no change from the 16% or from the 1V, I can also see this when I scope the inlet metering valve, the pwm signal alters when greater fuel is demanded and doesn't when the engine dies. According to Ford between 2004 and 2008 there were only 2 systems fitted and the test being to disconnect the inlet metering valve and watch rail pressure, one system the IMV will default open and one system it will default closed. I have the later system the rail pressure data indicates 2-3bar.
