I'm looking at a friends 2001 transit 2.0 diesel, which is a non start. Mate said it would cut out randomly then if he left it afew mins and tried again it would start, however this time it wouldn't restart.
I originally had fault codes p1564 and p1664. Using my solus pro I've cleared code p1564 but p1664 is constantly shown. Fuel gauge is showing 1/4tank, can see fuel in the little bowl by the filter. Cranked off the injectors, upon cranking I am getting fuel from each fuel line at the injector. Tried abit of easy start which it did try and fire on (used sparingly dont like using this). So I've def got a fuelling issue somewhere. (I believe)
I've checked the wiring to the pump can't see any visible chafing, removed the connection and checked pin on harness side which look ok.

Can anyone spare any advise before I condemn it, would rather be certain than sorry.

Thanks.
