Paul di Resta says he's hoping Force India's competitiveness returns for the Belgian Grand Prix after two point-less races in Germany and Hungary.
Di Resta, who scored 36 points in the first eight races of 2013, was unable to escape Q1 during the Hungarian Grand Prix weekend and hasn't qualified in the top ten since the Spanish Grand Prix in May.
The Force India driver originally qualified fifth for the British Grand Prix but was later disqualified after his car was found to be underweight.
"We need to get the car working for us like before," Di Resta said to F1.com
"In Budapest it was difficult to drive, but sometimes you get those tough weekends. Since then we have regrouped and analysed the previous races properly and hopefully this weekend will be a fresh start," he said.
"Everyone is determined to get back to the situation we had at the start of the year when we seemed to be punching above our weight."
Force India recorded its first points in F1 at Spa Francorchamps during the 2009 Belgian Grand Prix when Giancarlo Fisichella finished in second position after starting the race from pole.
It remains the only race Force India has finished on the podium so far.
Team principal Dr Vijay Mallya says he is also expecting a turnaround in the team's fortunes.
"The car has to be competitive on all tracks, but if I concede that Hungary was not ideally suited to us, by the same token Spa and Monza have traditionally been our stronger tracks," Dr Mallya said.
"So that gives me a little bit of a morale boost in saying that once we are on top of the game, we should restore our competitive position," He said.
Force India sit two points ahead of McLaren in fifth, who have gained 20 points on the team since the German Grand Prix.
