my jeeps will start fine and run good for awhile then it well start bucking and stalling and it wont start up right away. if i wait for a few min it will start back up. but it only does it here and there seems like its geting worse. i changed the plugs wires coil distribtor am geting good fuel pressure dont know what elles to do can some one help?

 

have you checked for codes even if the light is not on,and welcome

 

thanks working on a intro thread, no check engine light at anytime, but i will try to check, im thinking its the fuel pump

 

you should still check for codes just because the light aint on does not mean there aint none stored key on key off method search it

 

where is the obd port to pull codes on these jeeps?

Turn key on but don't start it. Turn key on then off 3 times leaving it in run position on the 3rd time. & count the cel flashes. Example code 12 will be one flash with a noticeable pause then two flashes a long pause will be between codes. 55code is end.

 

I have two but mines a 95. One by the ecm on inside drivers fender. & another underneath dash on drivers side.should be on bottom dash edge.

 

Did you figure it out? My 94 XJ is now doing the exact same thing
