I have a 1994 jeep Cherokee that I put a motor in out of a 1991 Cherokee, swapped engine harness and all plugged everything back in. I am not getting spark I have replaced the crank sensor and checked the distributor still nothing can't find a diagram to tell me where the coil pulls power from

The ignition coil is powered by the ASD relay and controlled by the engine controller. I attached the only schematic I could find below. I highlighted the relay, the power wire to the coil, and the coil.

Let me know if this helps or if you have other questions.

Take care,

joe
