If you can smell fuel under the bonnet, the rubber injector leakoff pipes have been damaged during the work. These go hard and brittle with age and leak when any work is done near them. Replacement is quick and cheap.

Another possibility is that the injection pump or valve timing have been incorrectly set whilst changing the belt. Unless the job is carefully done with the correct locking pins, it's easy to get the timing adrift. Injection timing is critical on the XUD - who did the work?
