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
Hello to all,
I drive a 2006 Nissan Titan lifted 4x4 flex fuel
Check engine came on and turns out I need to replace the cat converters.
With research I have been doing it seems like ALOT of Nissan Titans have this problem.
I do NOT I repeat DO NOT WANT to spend any more money than I already have when it could be something like a dirty cat converter or a faulty fuel pump.
Would really appreciate it if someone could help out so others won't have to suffer as much.
