code 43, fuel supply system, what does it mean?
Jan 1 I put a D16Z6 and P29 (I think thats the ECU, came with the motor from the same car) in my CRX. I had been getting a check engine light here and there which reset when I shut the car off. Of the few times I checked the code while driving, one was O2 heater, and I found what caused that and fixed it. I now get a fuel supply system code. What could cause that?
When I did the swap, I put new spark plugs in. A couple months ago I put new plug wires on. Last week I put a new distributer, cap, and rotor on it. The O2 sensor is an aftermarket Bosch which was put in at the time of the swap. I have an aftermarket exhaust manifold and cold air intake also.
Where should I start looking for the cause? The code doesnt come up every day, and its at random. Some days (like Monday) it might come on 3 times in 1 day, then it may go a month without doing it.
