Question about 1994 Audi Cabriolet
I bougth the car crashed at the back and after one year I have repaired it but still electrical have not completed at the back.Before repair i drove to garange four times after repair i drove a little and after coming back home the car wont start. Sometimes it start once and then dies.There is check engine light and my batterie light flashing rapidly. There is no spark and fuel pump not working and there is any signal from the ecu after diagnostic.
Your problem seems to be related to the power connections to the management computer system system..... Get yourself a multi meter and check the battery voltage first....have you replaced the battery?
Sometimes when a vehicle has stood for a long time, oxidization can build up between the battery towers and the terminals....this can cause intermittent faults, such as you're describing....but it's unlikely!....If you find that thats all ok, trace through the cables that connect to the computer....
......There will be an ignition connection....
......A battery connection, which should always have power, even with ignition off.....
.....There will be starter signal and ignition signal.....
.......Check the ground connections and then, and this is going to take time....trace through all the cables from each of the sensors and the controlled units....Make sure that the pump is getting power and that power is getting through to the ignition....
This is a very lengthy topic and I believe it may be a lot easier to do it in stages.....
This is the end of the first stage.....keep in touch and I'll give all the help that I can.....
