Honda code 43: fuel supply system

[bol]

anyone know what could cause this code? car is a '94 civic dx
it seems to run fine other than a slightly rough idle.

Had a friend with this problem long time ago. Apparently the code could be caused by a million things like fuel filter, fuel pump, fpr, o2 sensor, vacuum leaks...

Have you tried the FSM? They usually have a list of things to troubleshoot. Sorry I can't be more help here haha.
