2000 jeep cherokee sport cranks but no sparks all fuses good what could it be

SOURCE: 93 Jeep Grand Cherokee Won't start

The crankshaft position sensor was seriously problematic in those old jeeps. It's located towards the top of the bell housing slightly to the driver's side I think.

Pop off a spark plug wire, insert a screwdriver into the wire (hold onto the handle), hold a 1/4 inch to 1/2 inch away from engine and crank the engine. There should be a spark. If no spark you have a problem with either the ignition system or the ignition system control circuits. Generally if the computer dosen't see a crank signal you will not get a spark (if it doen't see a cam signal you won't get fuel). If no spark from wire try it on each wire. If not a single wire has spark, rent a scan tool from autozone or napa and see if there are any stored codes, also see if any codes come up while cranking. If you can't rent one you can buy a cheap one for under 30-40 dollars. If no codes and no spark the only thing you will have left to try is replacing the coil pack/s. If after replacing the coil packs you still don't have spark you will have to take it into a shop to have it checked out. The reason you would need to take it into a shop is because they will need to plug in a very expensive scan tool(1000-5000 dollars) that will show them all the sensor inputs. Hope this gets you up and running.

sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered

Try replacing spark plugs and battery, check the distributor cap.
