i have a b18c1 motor in a EG civic, and its throwing up a code showing the Fuel System Supply Code. What are some of the stuff i need to check to get rid of this code. I have change out the spark plugs and the rotors, and i pour in some fuel injector cleaner, but it still show up the code? what else am i missing to get rid of this code

 

Could be that your fuel pump is bad/going bad. You might want to replace it with a GSR pump or a Walbro.

:edit: It could also be that your fuel filter is clogged. Oh, are you using the fuel line that runs from your filter to your fuel rail that was originally on your civic or are you using the GSR line?

I STRONGLY suggest that you upgrade to the GSR line. I had a lot of problems using my stock civic line because it doesn't allow as much fuel through. You can get one of these at a reasonable price from www.sohfast.com

 

where is the the line located at?

 

It connects the fuel filter to the fuel rail, as said above.

 

oh im using the GSR line, so that makes my fuel pump is going out?

 

Maybe check the fuel pressure regulator in addition to the fuel pump and fuel filter.

Is your car running at all?

You could also check your relay.

 

the car runs, but the only time the check engine turn on is when i start to go up around 3 rpm

 

sounds like the TPS. but just a guess.
