Not a diesel driver so just a guess here, but if the inline pump is working hard would that be because it was struggling to pick up fuel??

I have read were the in tank pump is not transferring fuel but you have changed that.

So could the fuel pick up be blocked/damaged causing fuel starvation?

Thinking that myself hopefully get a chance next week to blow all the lines out, also got all the injectors tested 

Sorry if this has been covered before but I've searched for hours and can find any help,

Car drives fine of im driving slowly put won't allow me to put the foot down without dying, also has started to get hard to start.

So far I've changed 

Transfer fuel pump

Inline fuel pump & filter

High pressure fuel pump

Fuel rail sensors (both)

Checked the relay that starts the pump

I've also disconnected the fuel lines and made a make shift fuel tank to see if the problem was the fuel tank

Only other things I can think of is blowing out the fuel lines or change the ECM/ECU in the engine bay

Is there any fuses etc that I'm missing?

Also the inline pump is working more than it should (noisey)

Any help will be greatly appreciated

Thanks
