Your truck has the OBD-1 system. You can read all of the codes by jumping pin #2 to pin #6 of the self-test connector and counting the flashes on MIL (CEL) for the codes.
Or any $30.00 OBD-1 code reader will read them.
Or most auto part stores can read them for you also.
I would not take anything back to a mechanic that can not read codes.
