hi,
I bought a 1987 z31 turbo that has stood still since 1998. At retrieval it started almost instantly. Now at home it doesn't start anymore. Does anyone know why it suddenly stopped running or what could be the cause?
(New fuel has been added)
The two most common failures are crank angle sensor (in the distributor) and air flow meter.
These will show as fault codes on the self diagnosis function.
