SOURCE: 98 hyundai sonata obd II port has no power or comunication with my scaner
If you connect a scanner to the OBD2 port and the vehicle then runs fine? Then you have a problem with a ground. Top of the DLC is pin 4 and 5 that is the ECM body ground. pin 16 is battery volts 12vlts.
Testimonial: "THANKS for all your HELP I check the pins on the DLC and found ground on pin 5 and pin 4 was completlly dead trace all true out the ecm and i found inside the ecm board a short ground, I do remember my son telling me that he hit kind of hard a speed bump and after that car was very loud I jack up the car and look under the car finding a bend up muffler pipe and also a broken O2 sensor push up against the floor that seems that had short it out causing the ecm to blow a trace ground on the board the solution to fix all this mess was getting a New O2 sensor and a new ecm fix up the bend pipe and Now the car runs like new again THANK YOU for your help I hope this also will Help some one Else."
check the injectors with a noid light you may find a bad one. if not check the compression.
