Left Front Fuel Supply Circuit Failure?
I have a 1995 Honda Civic Ex I bought 4 months ago, well just recently my check engine light came on. I checked it, and the issue is the Left Front Fuel Supply System Circuit Failure. Im not sure exactly what it could be, any ideas?
I was thinking maybe a O2 sensor, bad injector....?

If I remember correct it was 45, I would have to double check with my paper work after I find it. Yes I did, it repeated it self

Well I guess it did, since I had to have Auto Zone do it since I was told 10 different things. I wasnt aware just to use a paper clip, and test it that way. So the lady as Auto Zone had done that for me. So I would assume it was done?

So it could be code 41 or 43. Any driveability issues? You don't want to troubleshoot the wrong code, so jump the service connector again to know what specific code is thrown.
You can clear codes from the ECU by removing the 7.5A Back Up fuse under the hood for a few minutes.

No driveability isses, other then it seems like I go through gas more often then before.
Ok so once I remove the 7.5A Back up fuse for a few minutes and insert it back in, then retest to see what the code is?

After clearing the CEL codes, drive around to see whether the CEL remains on while driving. If not, you are good to go. If so, pull the code(s) and post them.

Re: Left Front Fuel Supply Circuit Failure?
Okay, I will do that. Before I do that, I was going to mention that it doesnt come on all the time, or stay on all the time. Sometimes I can drive a week and it wont come on, and so forth. I will clearl the codes and then drive it.
Ill be back on in a few hours.

45 = Fuel system too rich or too lean
typical cause, failing O2.
less likely causes, bad injector, bad pressure regulator, failing fuel pump, clogged fuel filter, pretty much anything you can think of that may cause too much or too little fuel.

Keep a jumper wire or paper clip in the glove box. When the CEL turns on while driving, pull over, leave the engine running, and then jump service connector to pull the code(s).
