DAF LF 45 wont start - SOLVED!

Ordered a new PRV.
In the mean time I have 'modified the old one by putting some washers behind the spring thereby increasing the pressure on the valve. Now when cranking there is no fuel coming from the valve, but still no firing :imp:
I have checked can bus at brown socket on bulkhead. I have got 64ohms across the 2 cables and 2.4v from each cable when ignition on.

Where to next?
