I have a 96 impala and the code 0430 pops up on the scanner. what does that mean also where can I find the whole fuel pump module from

PO430 "catalytic converter system,bank2-efficiency below threshold" basically you are having a code pop up because of the cat or possibly a bad oxygen sensor......hard to tell without hooking up and verifying what part of that system is not working. More than likely its gonna need a catalytic converter on the bank 2 side.


The fuel pump sending unit? That is available all over. I would stick to GM ACDelco replacement. Check all associated wiring to check for bare wires as that is VERY common with the fuel system.
