Hi, I have recently bought an e24 as a non runner . One crank sensor had failed and has been replaced and the car will run of I jump the main relay between pin 30 and the 2 pins 86.
I have tried a new relay but no joy!
There is a live at the ( old style) ocb relay.
The other clues to possible culprits are that the on board computer fuse had blown and has now been replaced and has remained in tact, also there is no display on the ocb dash reader but I know the light bars are prone to failure......any ideas.
