how can i fix the ecu on daily 50c14 iveco van not stating?

If someone 'thinks' it is this or that,then invariably it will be money out of your pocket which will pay for it with no guarantees it will repair the problem,I take it the basics have checked,filters/timing belts/fuel delivery to injectors? I know there were problems on these with a fuel pump on the n/s chassis rail and I take it is cranking over ok
