Will Stevens will not be able to start today's 2015 Formula 1 Petronas Malaysia Grand Prix, Marussia have confirmed.
The team have been unable to find a solution to fuel system problems which first arose in FP3 and then prevented Stevens from getting out during qualifying.
"Sadly Will is unable to start today's race as we have not been able to get on top of the fuel system problem from yesterday," the team said on Twitter.
Stevens’ absence means today’s Grand Prix will feature 19 cars. His Marussia team mate Roberto Merhi will start from last on the grid.
