Re: 1977 530i no start

Thanks Mike. The distributor has one of these Pertronix electrical ignition systems installed - another thing I'm unfamiliar with. Does anyone know if the Pertronix kit replaces the standard pulse generator in these distributors. I've come across some suggestions that a faulty pulse generator in the ...

Re: 1977 530i no start

Thanks Mike. I adjusted the distributor a bit and the car started up. I don't understand why it being out of time would prevent the ECU from firing the injectors but I'm not that familiar with distributor systems.
