Kicked and stopped working !!

My friends vehicle 1997 peugeot boxer went home yesterday night, I heard a lot of different sounds from my car and then started to not eat gas, I said I would stop and run it, but I did not work, I wonder where the problem is.

no problem with the diesel or in the diesel pump: S

Which of the warning lights on the vehicle is on or on (stop or oil lamp) Did you check the oil and water? doesn't he start when he tries to start?

Thank goodness friends, we solved the problem, we looked for the problem with the master for 2 hours in the morning, and we found the problem is the pulse sensor on the battery, the pulse sensor did not turn off, it does not shut off the electricity from the stop sensor, it does not shut off, it does not immediately stop, or freezes the starter, I do not understand it. I wonder if this problem is due to fuel, I always get it from the same place, even if it is from fuel, I am a stimulus of new problems.
