Default CEL coming on... :(

I have not had any problems until now. Whenever I start my car (usually after it has set overnight) I can take off down the road and (driving easy, because I am going to work) the CEL will come on.

I shut the car off and turn it back on, it goes out. If I let the car set for any period less than 8 hrs, I can start the car and the CEL will not come back on.

It is on a 95 civic. The code that it brings up is 43. (four long flashes followed by three short flashes). I checked the code myself with the paper clip method. The code 43 is said to be the Fuel Supply System.

I am trying to figure out what I should do to fix this. I will be replacing my injectors with larger ones for the turbo. The fuel pump comes on when I turn the key (w/o starting the car). The CEL usually only comes on when the car's engine temperature gauge begins to move from cold.

Any suggestions on the things I should do?
I checked some other forums and found another person had the same code and they changed their fuel pump, fuel filter and had the injectors cleaned and still had the code come up (I am not sure if the ecu was reset though).

Any ideas would be great.
On the list of things I am thinking of that could be troublesome:
injectors
fuel filter
02 sensor?
fuel pump
leaky fuel line (I have inspected but cannot find one yet)
fuel pressure regulator
