Gentlemen Vectra c engine 1.9 cdti. The owner noticed while driving that esp, abs turned on and after a while the assistance disappeared. He drove to the parking lot and the car went out. Of course, the alternator was suspected. Disassembled and on the table. Voltage regulator for replacement - the current was between 10.5 -12.9 V. Alternator mounted and there is no way to check the charge because it does not ignite. So far ; prophylactically replaced battery for another, checked connections at the starter, replaced relay starter. Evident lack of starter relay control. On the jumper without a relay (3 from the front strip) the starter turns. A bundled wire at the engine control unit. Pin 72 brown / yellow appears after ignition. I was advised that still pin 70 gray / red there in turn appears a plus after ignition - about 12 volts. And here the stairs begin because if I give this pin (gray / red) mass through the neon lamp, the car turns but still does not start. The errors will be checked and I will give the result. Maybe you have some hints and what else to check. Greetings .
