car will not start

I have the ford duraspark set up and no spark when cranking.
(trying to start with key or with key in run position and jumping at the solenoid.)
Tried 3 other ignition modules. (2 are new, one out of another car known to be good)
Tried 2 coils (1 new 1 out of a another car known to be good)

for testing the coil and ignition module I have also wired them directly to the battery. Still no spark.

I will get one snap from the coil when the ignition module in first plugged in.

 

Found this on the net.
Time to check the distributor

 

I think the reluctor in my distributor is bad. it shows 0 ohms.

I have a spare one that was pulled from another distributor, it tests at 640 ohms.

 

Glad we could help! was going to say check dist. you saved me from digging that info up!
