Xsara Picasso without injection pulse

Hello everyone. My HDI 2.0 Picasso with Bosch injection of the year 2002 does not have injection pulse, the low pump works and has a good diesel pressure, and the box that controls the preheating spark plugs does not control if the spark plugs are connected, if I disconnect them if it is. The scanner among other codes detects the P1517 that indicates defect in anti -bar. Recodify the key correctly, the BSI recognized it without problems. Does anyone have an idea of ​​where to look for. Thank you

If the antiarranque failure is not going to start verifies that fault first than missing greetings
