Is there any link between Islam and Zoroastrianism?

nope

Since Zoroastrianism is the first "modern" monotheistic religion (that doesn't involve sun worship or king worship), I would say that is a pretty big linkage right there. That and the concept of an afterlife, between good and evil.

There are both monotheistic religions and Zoroastrianism was the main religion of Persia, now a Muslim zone. But I don't think there is any influence of one on the other.

In the 7Th century, the Sassanid dynasty was overthrown by the Arabs. Although some of the later rulers had Zoroastrian shrines destroyed, generally Zoroastrians were included as People of the Book and allowed to practice their religion. Mass conversions to Islam were not desired or imposed, in accordance with Islamic law. However, there was a slow but steady movement of the population of Persia toward Islam. The nobility and city-dwellers were the first to convert. Islam spread more slowly among the peasantry and the divans, or landed gentry. Later, the Giza, a poll tax imposed on non-Muslims, probably accelerated the process.

Well, kind of. Zoroastrianism was the state religion of Persia until Islam took over. Today there are only a very tiny population of Zoroastrians living in isolated communities in Iran. So Islam "displaced" Zoroastrianism. Also from a purely anthropological standpoint, Zoroastrianism might have been the first Monotheistic religion (Though not a "religion of the Book" like Islam, Judaism or Christianity) and this may have influenced the creation (or maybe discovery) of the other monotheistic religions.

No. Zoroastrianism predates Islam by several centuries. Zorastrianism was practiced in Persia (present-day Iran) and parts of what is today Pakistan, India and Iraq. At the time Islam swept across those parts of the world (the 7Th & 8Th centuries CE) Muslim thinkers considered Zorastrians to be "unbelievers." Subsequently, some Islamic jurists agreed that Zorastrians should be considered as "People of the Book" along with Jews & Christians. This interpretation of Islamic teaching, however, was never universally accepted
in Islam. They are two very distinct religions.

an interesting religion, perhaps a remnant of a true prophet of God, but much of what remains is not enough to guide a life upon due to lack of doctrine

Some people think so:
