Attention: before carrying out any work on the engine, disconnect the negative cable from the battery. If for some work it is necessary to have voltage in the on-board network, care must be taken not to cause short circuits on the «mass».
Attention: before carrying out work related to the depressurization of the fuel system, the pressure in the system should be reduced. To do this, let the engine run for 10 seconds with the fuel pump off. Remove the fuse to turn off the fuel pump (see fig. T250 2.003).
