MERCEDES BENZ S320 FUEL PUMP PROBLEM

1996 Mercedes Benz S320 • 120,000 miles

Pulled fuel pump fuse and reinserted when checking other fuses. Car engine light went on. Had autozone check engine light on. Fuel pump and multi misfire codes. Autozone stated when fuel pump fuse pulled it caused a computer fuel pump error reading. Autozone stated the misfire will disappear after driving car for some period of time. Ow long will it take for the misfire to resume normal?

That is strange, I would just disconnect the negative batt cable and that should reset the computer and get rid of any issues.

Good luck.
