Coil does not get power I've changed coil but still nothing i don't know where to look for the problem the engine does turn over just no spark

Based on my experience with many of these crank/no starts with Grand Cherokees, I would say it is the crank position sensor. I have replaced many on these vehicles and it is in an unpleasant location. If the PCM doesn't see the crank signal from the CPS, it will shut down the ASD(Automatic shutdown) relay causing a no start condition because it cuts power to the ignition coil, fuel pump and injectors. Check power at the coil and one of the fuel injectors. If you don't have power at both, the ASD is shutting both down because of the PCM seeing something it doesn't like.

Usually on the 96-up vehicles, I have a scantool connected, I crank the engine and look at the live data related to engine rpms. If the CPS is working, I will see rpms show up during cranking. On a 93, you will have use a multimeter at the connector. The CPS is located on the top, back of the transmission bellhousing on the driver-side, but the harness runs along the back across to the passenger side.

You may need a shop manual for the wiring diagrams and test procedures.
The coil is powered from the ASD relay on the dark green and orange wire. It is grounded from the computer.
