Can codes be pulled from 95 jeep without a scanner

Yes. Turn the ignition switch to ON, do not engage the starter. Do this 3 times. On the third time leave the key in the ON position and start counting the number of times that the Check Engine Light flashes on and off. There will be a slightly longer pause when it is flashing out the next digit. Then go to http://autorepair.about.com/library/ts/obd-i/bl-dtcs-75a.htm and see what your code(s) mean.
