E28 Wont Start - No Spark
My friends 535i (e28) won't start.
(1) Car cranks over fine. Plenty of juice in battery.
(2) Fuel pump is working and engine is getting fuel.
(3) Airflow meter is working.
I removed spark plug and plug does "not" fire.
(4) I am guessing cap and rotor as next to look at.
Can anyone help?
E28 Won't start No Spark - Need Help !!
The car is a 1988 535is
I have a running 1988 535i so I have parts that I can swap.
Here is a list of the parts that I have confirmed to be ok:
1) Replaced Bosche Cap and Rotor with new from BMA.
2) Swapped Coil and Motronic.
Car still wont start.
I have removed the Crank Positon Sensor but I am not sure if this
is going to solve this issue.
The car has plenty of cranking power and the fuel pump is working.
Is it possible the coil is not getting 12 volts from the battery?
Any help would be great.

MRBMW1 Did you mean the "Reference Sensor" ??
This 535is has a "Crank Position Sensor" which is in the front of the engine that has three wires to the diagnostic port. It also has a sensor near the back of the engine. See attached picture.
