Fuel Supply System defective or malfunctioning fuel supply system, i have replaced almost all aspects of the fuel system and im still pulling the same code. ive replaced the fuel pump and sock, fuel filter, injectors . all i havent changed yet is the fuel rail and fuel pressure regulator. and also in first and second gear it sputters when you hit the gas. any help would be aprciated.

 

Normally this is also caused by a bad or failing o2 sensor. When I had this code a couple years back it was because I had an open wire near my access panel behind my seats

 

yea i checked all wires that go from the float and pump all the way back to the main relay. ive never heard of an o2 sensor making that much of a problem but seeing what its job is its possible ill have to check that out thanks man any other input ?

 

bump

 

where is this wire panel ur speak of?

 

I have 92 accord ex and it was a intermittent o2 sensor failure!!! Runs perfect now! I got 43 sometimes, but cel wasn't always tripped.
