So I check my cel and it comes up number 43, fuel supply. What the hell do I do to fix it??? My car runs fine up top, still runs hella rich but the car won't idle, I'm assuming a crazy fuel pressure at idle. How would I check my fuel pump and what all do I need to check to fix this?!?!?!?! I realize I could hook up a fuel pressure gauge and see what it says but there maybe something else wrong, not the fuel pump, causing poor fuel pressure. Any help would be appreciated.

Oh and for those who don't know, its a 94 accord with a 2000 h22 running compete stock Accord fuel system(haven't had any fuel problems for a year now since the swap with stock fuel system).

 

Reset your ecu, see if it comes back

 

screw that...i'm not messing around with a fuel supply code....and my idle won't get any better so obviously its gonna keep throwing the code.

 

umm okay don't then, your idle while suck while the car is in safe mode. If there is a problem it will come back. Restting the ecu is not bad.

 

OK, resetting the ECU won't fix the problem, I've reset it 10 times before, its not in any safe mode for this particular code, the car runs the same.
