[Engine] non starter/electrical.

[split rivet]

Hi there ...i was wondering if any ones got a clue what this fault is
51 plate 2001 1.9d berlingo...
Turn key 1 nothing turn key 2 only oil light and airbag turn key 3 it turns over but no start, oh yeah the blower wont work either.
The vans been ok for years, the only recent work was to clean out the egr valve, it ran fine after doing that but now nothing,ive checked all the fuses twice and cleaned all the earths, ive even done the bsi reset but not sure if i did that correct as i dont have central locking, anyway this has really got me foxed????
Any ideas......
