Pacheco has spent his entire career with one of El Salvador's biggest clubs, FAS. After moving through the junior ranks and into the first team reserves, he was given his first chance to play in the Salvadoran Primera División in 2001. He made his professional debut on March 3, 2001, in a league match against C.D. Municipal Limeño. In 2005, he was named club captain, and has been so ever since.
On February 18, 2009 it was announced that New York Red Bulls head coach Juan Carlos Osorio had traveled to El Salvador with the hopes of bringing Pacheco to Major League Soccer. Pacheco had been scouted for several months, most notably during FIFA World Cup qualification matches, as well as during the UNCAF Nations Cup tournament. It was initially announced that Pacheco signed with New York Red Bulls on March 5, 2009, but due to difficulties surrounding his International Transfer Card  the New York front office did not officially announce his signing until April 17, 2009. In the meantime Pacheco started training with the Red Bulls on April 7, 2009  and after his official signing made his first appearance on April 18, 2009. After a bright start, Pacheco struggled on the field for New York, and the team terminated his loan deal before the end of the season. Pacheco signed a two year contract with C.D. Águila on June 30, 2010. However, he left the club just one year into his contract with Aguila to join Isidro Metápan starting with the 2011/12 season.
Pacheco began his international career with El Salvador's U-20 national team in 2000. He took part in the 2003 CONCACAF U-20 Tournament, which was held throughout 2002. Unfortunately, El Salvador failed to qualify for the FIFA World Youth Championship that was to be held in the United Arab Emirates.
Again, that same year, Pacheco received his first cap with the men's national team. This was on November 17, 2002 in a friendly match against the USA. Pacheco scored his first goal for El Salvador, off a free-kick vs Costa Rica in a 2003 Gold Cup Quarterfinals match. Pacheco is currently the top most capped player of all-time for El Salvador with 86 caps.
On September 20, 2013, Pacheco was one of 14 Salvadoran players banned for life due to their involvement with match fixing.
