90 jeep 4.0 Cherokee-no spark?
 

90 jeep 4.0 Cherokee-no spark

No spark fro the coil wire
No spark after replacing the coil and the ignition control module
Could it be the sync signal generator or
is it the electronic control module?

Thanks for any help

And the other 1 percent, the ground strap from the rear of the engine to
