Does the vehicle have spark ? If it does it is not the crank sensor . The ignition switch supplys power for the fuel pump relay directly ,ASD has nothing to do with it . The PCM - engine computer energizes the fuel pump relay by supplying a ground - if it see's a crankshaft postion sensor signal an if no anti-theft system problems . Do you know what a wiring diagram is ? Here free one's http://www.bbbind.com/free_tsb.html Enter vehicle info . year , make , model an engine size . Under system click on engine , then under subsystem click on fuel controls . Click the search button ,then the blue link. Third diagram down.

change the computer .... PCM get a used one it fixed mine had same problem

check your transmission fluid,the motor will stall when fluid is low

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.
SOURCE: what weight oil does a 96 jeep cherokee use
dont know for sure how true this is but ive always used 10w30 in them.sometimes it will tell you under the hood on the sticker with the info or your nearest oil change station has the capability to look up what the manufacturer calls for.I think all older chryslers ran 10w30 though

My 99 Jeep Cherokee keeps shuting off when I am taking right turns. If anyone can point me in the right direction that would be awesome. I am really stumped.

Have you checked the pump relay in the power distribution center???
yes i have tested it and seems fine. i just found something called a crankshaft position sensor that i am going to test tomorrow.
Good idea to check crank sensor. that sends info to the computer which sends a signal to the asd relay...that turns on the pump relay. the asd relay will also shut down the injectors if there is no signal from the crank sensor. Get a wiring diagram and you'll see how they work together.
Also make sure your grounds are good or nothing will work as it's supposed to.
thanks for the info. i will check the grounds. where do you get a wiring diagram?
