Hi Petr,
Sorry to hear that you are stuck in such a difficult location. I can not say anything about the problem with the oil pump, however can comment on the starter portion of the issue you are experiencing with your van.
When you turn the ignition key on, the click you are hearing is the starter relay which is, on most Ford products mounted on the firewall, providing that the battery is strong enough to spind the starter, if nothing else happens, that sounds like your starter mounted solenoid or the starter motor needs attention. Good luck
