Hondata

Hello, I purchased a 95 GSR with a JR supercharger and hondata ecu. Recently my check engine light came on and I checked the error codes and got a 43 & 16 Both are related to my fuel system. The car ran fine I didn?t notice any problems.

My fuel pressure @ idle is around 31psi (maybe low?)

I pulled the neg on my battery for about 5 mins put it back on and started the car fine. No light no error, I don't know If I should be worried about this problem or not.

Any suggestions as to what I should check out?

On a side note my fuel gauge stays at full until there is about a half a tank left then goes down quickly and uniformly. I don't know if this prob is related but I thought I'd mention it.

Forgot to mention I have hondata 450cc injectors. I checked they are all firing.

Both Honda's I've owned have done the same thing with the fuel level gauge, so I don't think that's the problem. 31 psi is kind of low for you to be running 450cc injectors...I would try bumping pressure up to around 38 psi and see if that helps. If the code went away after removing the battery and hasn't come back, I wouldn't worry about it too much.
