i got a CEL...code 43...it's the fuel supply system
how can i check to see what's causing this?

sounds like the pump ... but if that wasn't working t5hen your car won't run... injectors maybe?? no those have their own code ... fuel filter maybe ?? was that changed at all....?

never changed the fuel filter since i've had the car...
i guess it's worth changing...
the problem in my fuel supply system is causing me to overfuel the engine (hopefully that makes sense)...what can cause this?
injectors? (but would a sensor, sense injectors?)

Are you sure you are overfueling?? If so, check the coolant temp sensor and air intake temp sensor, but odds are there is something else wrong with the system. CELs constantly are usually emissions things, while flashing ones are major failures.
