Montoya was born in Bogotá, Colombia, where he was taught the techniques of karting from an early age by his father Pablo, an architect and motorsport enthusiast. Montoya moved to the Colombian Formula Renault Series in 1992, while racing there he won four of eight races and had five poles. The same year he also participated in the U.S. Skip Barber driving school, and was hailed by driving instructors as being one of the best pupils to ever come through their school. 1993 saw Montoya switch to the Swift GTI Championship, a series he dominated by winning seven of eight races and earning eight poles. In 1994, Montoya raced in three separate series: The Sudam 125 Karting (won the title), Barber Saab Pro Series (finished third in points, won two races), and Formula N in Mexico (won the title). He graduated from the Colegio San Tarsicio in Bogotá in the same year. Montoya developed into a strong qualifier, in some cases taking 80% of a season's pole positions. For the next three years Montoya raced in various divisions, continually progressing upward. He raced in the 1995 British Formula Vauxhall Championship, winning three races and finishing third in the championship. In 1996, he raced in the British Formula 3 with Fortec Motorsport, winning two races, and finishing 5th in the championship points standings, as well as taking part in events in Zandvoort, Netherlands and Silverstone.
