code 43?
was just wondering if anyone on here has had the same code pop up. it says the code is Fuel Supply System: defective or malfunctioning fuel supply system. now i have replaced the fuel filter, pump, added a fuel pressure regulator, vtec controller, and it is still throwing a code. thanks for the help.

Re: code 43? (Echo7847)
the book says if your car is running fine and has the code check your o2 sensor...
if it has the code and is running like crap...check your fuel system...
