E28 Wont Start - No Spark

[Mr Project]

If you pull the coil lead and have someone crank it (briefly!), does the coil 'snap' and spark?

I swapped the coils from a running 535i (e28).
The coil is ok as it worked in the running car.
Using a volt meter I get 12 volts to the coil.

I removed a spark plug and had my friend
crank it and observed no spark from the plug.

Success!! Thanks to all for your input. I swapped the reference sensor and that did the trick. Installed new one from BMA along with new cap and rotor and new plugs and this 88 535is runs great. Idle steady at 800 rpm. Thanks again to all.
