Hmmm!
What resyncer did you buy? Are you certain it's for the motronic engine & not the gems?
Have you tested the fuel relay under the bonnet? You can swap them around, colour for colour.
I had the same problem on my 4.6. Was convinced it was the crank sensor; but as Rick says I swapped the relay and hey presto, its been ok since. Worth a try.
