With all the parts you've had engineers randomly change you could of bought a new burner. That's another option, many decent engineers have spare burners for problem child situations like this. Maybe if they have a sound Sterling that could be fitted for a week, at least then you'll know if it's a fuel or burner problem. If that's not an option then they need to go through what I've said to rule out possibilities. If I attended and couldn't find the fault first time, after replacing the pump as you said was then I shouldn't be charging you for return visits
