Marussia will not make Day One of pre-season testing due to a "small but frustrating technical issue."
The team had hoped to be present from the start of the Jerez test but have confirmed that they will miss at least the opening day.
However, the team, who have switched to Ferrari power for this year's Championship, could yet miss more days as it is not known how long it will take to solve the problem.
"The #MR03's testing debut is subject to a delay while we resolve a small but frustrating technical issue," the team stated via Twitter.
"The aim is to solve the issue as quickly as possible and send the car on its way. We're all set up here in Jerez ready and waiting for it."
