Question about 1997 Jeep Grand Cherokee
Here are some possible reasons:
Park/neutral switch is open.
Poor ground connection to starter.
You can test the park/neutral switch by either jumping the solenoid (connect the hot terminal to the start terminal to see if the starter cranks--if it does, the ground is good) or by interrogating the starter relay socket. To interrogate the relay socket, use a 12 volt test light connection the clip to battery positive. Probe the socket terminals with the test light. If only one terminal lights the light, your park/neutral switch is bad or the start wire to the solenoid is bad.

Sounds like a bad starter, why did you replace the crank position sensor? If the engine will not turn over at all and it sparks with trying to jump the solenoid with a screw driver it seem as though the starter is bad. First you solve the solenoid problem when you jumped the solenoid with a screw driver sending fire to the starter. Check the cable connections to the starter if they are good replace the starter this should fix your problem.

Could be a bad connection between the battery and starter. Starter solenoid, or neutral safety switch if it is standard transmission.
Check for power at the solenoid.

Try putting the car in neutral and starting. If its a manual trans it might be the clutch pedal safety switch or it may be something as simple as a loose battery connection.

fuse 8 40a supplies power to starter relay and ignition switch, to close the starter solenoid and engage the starter which draws directly from the battery. check to see that the starter relay is closing, if not ensure that the park neutral switch is not faulty (open circuit), it provides path to close relay (ground side) on the 85 - 86 terminals. if the starter relay does not close the starter will not run. if you have a spare relay swap out the relay for a quick fix attempt. hope this helps
