Partner 2.0 to stop hdi and not to eat gas

I got 2.0 hdi partners 1 week ago.

While the vehicle was on the road, I used it with a slow speed and stopped when I pressed the brake.

I hit the starter again. He did not. It started with a little too much starter for the second time and then stopped again.

I wonder why the problem is caused.

2 days ago the glow plug and fuel pressure switch were changed.

I request your help.
