Playing on the campus of San Joaquin Memorial High School, Fresno made a blistering start to their first campaign, scoring eight goals in back-to-back wins over Nevada Wonders, California Gold and Orange County Blue Star, with standout striker Orlando Ramirez.
Fresno's impressive early season form also saw them qualify for the US Open Cup, where they made it all the way to the fourth round with victories over Chico Rooks, Utah Blitzz and El Paso Patriots, before they finally fell, 3–1, to Los Angeles Galaxy.
Fuego's Latin American connection, led by Ramirez and Fabricio Codeceira was influential and by the end of their debut year they were sitting proudly atop the Southwest table, ahead of Orange County Blue Star on goal difference.
2004 saw the Fuego move to a new home at Fresno Pacific University, but the change did not affect their on-field performances, which included two 5–1 thrashings of the San Diego Gauchos, and nine-goal haul over 2 games against California Gold.
Orlando Ramirez, Edgardo Contreras, Jose Luis Espindola and Milton Blanco continued their free-scoring exploits, and by the end of the 18-game season they finished just four points behind divisional champs Orange County Blue Star, and for the second year in a row made the playoffs.
Veteran Edgardo Contreras and new signing Amaury Nunes were the top marksmen, knocking in 8 goals each, while Brazilian Fabricio Codeceira was a midfield dynamo, registering 7 assists for the season.
Fabricio Codeceira and Amaury Nunes remained potent in front of goal, netting 18 times between them, but their spotty form was their downfall, and by the end of the season head coach Jaime Ramirez's men were a distant fifth behind league leaders Orange County Blue Star and Southern California Seahorses.
2008 was a year of continued growth for Fuego in business terms, unveiling a new logo, and building on their new 3,000-strong fan base and their relationship with the Fresno Grizzlies at Chukchansi Park.
By this time, Campos had been spotted by international scouts, and before the end of the month he was off to GAIS in Gothenburg, Sweden, to begin his professional career, leaving Fresno to find a replacement marksman.
A general lack of firepower – the result of losing Pablo Campos and Amaury Nunes to the professional ranks – and a frustrating tendency to inconsistency kept the Fuego on the back from their opening game, which they lost, 1–0, to divisional new boys Hollywood United Hitmen.
They lost their opening game of the season, 3–0, to the Hollywood United Hitmen, bounced back to beat the Ogden Outlaws, 4–0, but then were annihilated, 7–2, by Orange County Blue Star.
