Salvage BMW 850i purchased 3 months ago has been repaired

This classic BMW originally registered in November 1991 has now been returned from the garage and is back running again. Many of these BMW 8 series came off the road due to the problems covered in this video. If you have a barn find, salvage (like this one) or BMW E31 8 Series unable to start, be sure to give this video a watch as there are loads of useful tips and tricks to get your BMW back up and running It goes without saying that #m539restorations videos on the BMW 850i are central to the ability to have restored this BMW 8 Series. I am also grateful to the technicians whose expertise helped diagnose difficult and what are now out of date probelms with the electronics, the solution I was told lay in old manuals on the car, one Friday afternoon they were at sixes and sevens trying to diagnose the start problem and it came down to the Fuse Relays & Modules. Often when you find a salvage one of these cars (as I did ) the car has been through several garages who have failed to find the problem. I was told the car had an immobilosor problem The purpose of this video is simply to provide information about what it took to fix this BMW 850i, the car still needs some (a lot of) suspension work so I am not driving it in country lanes etc. yet! The 850i will be parked over the winter, hopefully I will shoot more detailed content in the new year Timecodes 00:00 Intro 01:30 Two Yuasa Batteries 01:54 GM II Module - General Module 05:44 Fuel Lines 07:32 Fuel Filters 08:52 Fuel Pump Assembly 13:27 Ignition Lines 14:54 Fuel Injectors 18:55 Pound Coin On Engine 21:36 Spark Plugs 25:42 Distributor Cap & Rotors 27:09 Fuse Relays & Modules 30:48 Onboard Computer (OBC)
