If the fuse is not blown, you will have to diagnose the system with the information provided. Bad fuse OR bad relay OR bad wiring connection OR bad pump (in reply to clubmia85) Post #: 11

If it comes back within a week, it may need repair. You may need a code decoder list. This is available on Alldata.com with a subscription. I have an X300 and having a code reader has saved me thousands of dollars in unneeded repairs from erronious codes. It would be the best tool you ever bought. I have not heard of many cases where the catalyst was really bad, it''s often the O2 sensors getting weak and giving wrong signals to the ECU that the catalysts are bad. If a downstream sensor gets lazy, it can tell the computer that the catalyst is not cleaning well when it is not true. I would be suspicious until I read the codes myself and this is because I was a tech at one time!
