Report: Catalytic Converter Damage Due to Weak or Failing Fuel Pump
Nissan Titan Problem
A weak or failing fuel pump can cause power loss due to lower fuel pressure and lean mixture conditions. This rarely causes a Check Engine Light to illuminate and should be repaired to avoid catalytic converter damage.

Both my cats have failed along with all four o2 sensors. In Nov 2010 before the recall on the computer module mine failed on the way to work. Now the cats and o2 sensors. Currently the battery drained very fast and it won't start just repeated clicking noise. Break pads have been replaced twice since i got it
