Im getting codes from my comp that r 12 42 43 55 can anyone help me with these codes

 

Code 12 means basically during the last 50 key on Key off cycles that you disconnected the battery, probably to change a terminal or could have gotten loose it's self
Code 42 Fuel Pump relay or auto shutdown relay (ASD) control circuit indicates an open or shorted circuit condition
Code 43 Multiple cylinder missfire detected.Peak primary circuit current not achieved with the maximum dwell time.
Code 55 Completion of fault code display on CHECK ENGINE lamp. This is an end of message code

your code 42 code be your fuel pump might be ready to go or just as it says a short somewhere. and your code 43 code be a bad plug, Good Luck !!

 

Concur with FuzzRacer...

Take the little guy on down to Advanced Autoparts, Autozone, Oriely or any other store of that nature and hook yourself up with an OBD II Reader. That will give you a little bit more in-depth information on what your problem is.

 

You gotta love the OBD II, one day im going to make a good investment and buy a scan tool, I think the one I want is called " Scan Pro"

 

Thanks for all the help guys
