Force India returned empty handed for the fourth time this season with Vitantonio Liuzzi finishing 12th and Adrian Sutil 16th at the Italian Grand Prix in Monza on Sunday.
It is third time in the last four races that Force India has failed to get a point in an otherwise impressive season.
Before this race, Force India had returned without any points from the Chinese, German and Hungary Grand Prix.
Sutil, who began 11th on the grid, was pushed back to the rear after an opening lap trouble which also forced him an early pit stop, but the German driver raced amazingly to move up.
He switched on to hard tyres and moved to 17 by the lap 18. In another five laps, he was in top-15.
With the 16th-place finish, Sutil dropped one position to 10th.
It was a home race for Liuzzi, who started on P20, and the Italian made full use of the opening lap mix-up, which also saw Mclaren's Lewis Hamilton crashing out of the race.
The Briton was too aggressive at the first chicane and collided with Ferarri's Felipe Massa, damaging his right front wheel.
Liuzzi soon was in 12th position and maintained that till he took first pit stop in lap 32 and joined the race back at 13th position.
Ferrari's Fernando Alonso, who started at the Pole, won the race after trailing Mclaren's Jenson Button's in most of the GP.
