To check the codes on a 1995 you need an ODB code reader, then you connect the code reader to the ECM (computer module) that is located under the hood.

You find more details and explanation on how to read codes on the website below:

This may or may not work for your vehicle but it does not do any harm to try. This will only work if you have the LED type display on your panel: Have a pen or pencil and a paper handy. Put key in ignition, turn to "on" position but DO NOT actually turn engine over, turn back to "off". Do this 3 times in a row and on the last turn, leave in on position. If this works you will see "P" and some numbers (example: P 0455). Write these codes down. When the display reads "done", then turn to off and remove your key. Google the codes you get using keys words such as " 1995 Jeep Grand Cherokee OBD code pxxxx(enter code number instead of x's) and go from there.

Hi, Check the fuel pump and fuses. Sounds like no fuel is getting to injectors. Also chek for computer codes this will give you an idea of where to look. Good luck.
