Mk6 transit panel van 280SWB won't start electric haywire!!!

Gonna try to find someone with a code reader to help but based on all info already supplied any other ideas spring to mind?? Feel like we have checked & rechecked everything

So had the codes read got P1665,Injection Pump Control Module Communications.
How do i check that the edu is broken or just a communication error??
Thinking about sending it off to a company I've found so they can fix the edu but like to check if i can that it's broken to start with.
Thanks in advance
