Haas was forced to end the first day of the second pre-season test early following a 'fuel system issue', according to the team.
Esteban Gutierrez completed just 23 laps prior to lunch, having spent the majority of the time in the garage. He admitted the problem was "not straightforward" and the team were struggling to fix it, but hoped to get him out in the afternoon.
However they failed to do so and instead chose to call it a day early, giving their mechanics extra time to understand the problem and to put a permanent fix in place overnight for Wednesday when Gutierrez will drive again.
