I have encountered a Fuel Supply System code on my Ls/Vtec motor. wat are some possible causes or fixes i can do about it.. If any one knows anything an can help me out, it would be helpful ok Thank you

 

My car had the same problem, i was reading what one of my friends sent me, he is a dealer technician for honda and it says it can be some short in some wires to the injectors or to the ecu, the ecu might be bad (try getting someone else's, a donor ecu, and try it out and see if you get the code, and/or the O2 sensor is bad, if you need some more info i can get you the print-out with exact instructions on what to do, you can e-mail me redsihatch@yahoo.com.

 

Hey man thanks i'll try it out an c if anything helps out...but thanks for the advice...i'll get back to u on this one..

 

did you ever find out what your problem was?

 

Did not fined out yet but when i do i'll let u know

 

Anybody figure this out yet? I popped the code 43 2 or 3 times in the last week, and my recent 00 ls swap has been running rough since i put it in.

 

possible it could be your fuel pump not sending out enough fuel or the filter on the pump is clogged. check and see what your pressure is at. make sure that you're up to date on your maint.

 

make sure you fuel system is in good working order.. possibly your fuel filter.


I throw the code once every few months.. When i shut her down, and start it back up its gone for awhile.

 

My civic and integra both used to get that hair up their asses every once in a while. but mine went away.

 

It could be:

1. the O2 sensor itself
2. the a/f mixture that it's sensing is outta whack compared to what the ECU wants to see
3. the wiring

 

ttt, code hasnt come back in a week, but car is running much worse

 

What help can we be with no info from you? 00 LS swap isn't nearly enough to go off of...
