New 635csi owner can't get it running! Bromley, Kent

[W55ksy]

Hi guys - this old girl was standing for years before I had her recovered to my house. I am trying to get it started but can't get a spark. There doesn't appear to be power at the coil. What needs checking before the coil any ideas? I've had the ECU apart and doesn't look too rough!

Any thoughts appreciated- I am a fairly basic enthusiast so keep it simple!

replace the main relay ( ecu relay) probably good insurance on a car that sat for a while. Check the ohm reading on the reference sensor. Do you have the Bentley manual for the e28 ?

You'll have to wade through this article, but all the information is in there. Your car uses the same system as the 85-88 535 as far as the fuel and ignition http://www.hiperformancestore.com/motronic.htm
