Why doesn't the coil get spark?

(1991 BMW 535i)
I recently got a 1991 BMW 535i. My son and I were planning to turbo it and making a great project car. But in order for us to do that we have to have a running car. The car had a old viper alarm system that fried the wiring and we took it out. But still we get no spark from the coil, does anyone have any answers?

There is no "coil fuse" on this vehicle. It is internally fused in the DME (current controlled internal circuit breaker). You should take this very sophisticated, technologically advanced piece of engineering beauty to a trained BMW Specialist (a specialist is someone who only works on one make of vehicle). There are many qualified independent, as well as dealer choices out there. Remember, there is no such thing as a Euro Specialist, or a Japanese Specialist, or a Domestic Specialist, or even a German Auto Specialist - the term would be an oxymoron. A German Auto Specialist would have to be proficient in seven different makes - this is not possible anymore "Jack of all trades, master of none".

There needs to be a signal from the front crankshaft sensor going to the DME for there to be any coil activation.
