91 xj flooding out
hey guys my 91 xj 4.0 is flooding itself out. if it is dead cold it will fire right up but if u let it run a few mins and cut it off it will most likely not start back up and man u can smell the gas if u unplug the fuel pump relay it will crank and run real rich for a minute smokin like crazy then plug the relay back in and it will stay running but not good. before you ask yes i have changed the maf sensor and done a full tuneup fuel filter, plugs, wires, rotor button, distributor cap etc. Any ideas would be greatly appreciated

That was 11 years ago.
I would suspect it's most likely a split hose from the intake manifold to the MAP sensor.
