Astra G VP44 PSG5

[Cunder79]

Hi All!

Astra G '99 X20DTL VP44.

The problem is the following:  By the one of the mornings the engine did not start. I have read an error message: p1631. I changed the transistor in PSG-5 into IRLR 2905. Then I have got an error: p1651 and the engine did not start after all. After a little time there was no 5 Volt on the leg of the voltage regulator and the error message p1650 and p1651 has already appeared.  I have got a controller (it was not operating in another car) and put it in and the error message was p1651.  I changed the voltage regulator IC ((78S05) but the error message stayed and the engine cannot start.

THX for All!
