Question about 2001 Jeep Grand Cherokee
Changed CPS and cleaned battery terminals and grnds. Cleaned starter connections and tried spare key.
Get a DTC reader with live data option. Watch the live data while cranking and see if your values change. If they don't, it's either a blown ECM fuse or a bad ECM.
If the values are changing, spray carb cleaner into the throttle body while cranking to ensure fuel delivery. If it starts check piwer to the fuel pump. If power is good to the pump, I'd replace the fuel pump assembly with a jeep pump.
If it still won't start, check your spark. If there is no spark, I'd replace the crank sensor. At this point all the basics are there. The only other concerns would be internal. Low or no compression or timing
