Jeep Fule problem

I have a 97' jeep Cherokee it has 220,000 miles on it. It won't stay running unless I keep my foot on the throttle. Any one have any ideas. It'd be greatly appreciated it's the only vehicle I have and I need it for work.

I would suggest you go to Auto Zone or Advanced Auto. Get a loaner fuel pump gauge for your vehicle. Check the pressure and compare to required fuel pressure. I would also get a free check of the codes on the engine.
