1984 4k - no start

[Bares, Vittorio]

So, has new wires, rotor, cap, plugs - was running fine - then about a
week ago, while driving it - it just stopped running.

 

I cleaned the contacts on the coil - started again, but wasn't running
well. Almost as if it was running on 4 cyl (it is a quattro 5cyl :-)). I
was trying to diagnose by pulling one sparkplug at a time while it was
running, not much change when I did so - consistently for all 5 plug
wires.

 

Pulled the plug on the temp sensor in the rear of the head - no diff.

Pulled the plug on the sensor that is on the fuel distributor - no diff.

 

This morning - no start...

 

No spark.

 

I'm thinking hall sensor??
