PR4 CEL #43 Fuel Supply System
I'm throwing this code on my 91 LS ECU, I'm assuming that it means the fuel pump needs to be replaced, and I'm gonna go ahead and do the fuel filter also. Those componets, to the best of my knowledge, have been in there since the car was new. I'm getting a bog/hesitation problem also, same one that I had on the previous LSVTEC, but that PR3 ECU never threw a code though, but I'm leaning towards the fuel pump.
Does anyone have any experience with this code and if the fuel pump should be the source, like I'm suspecting?
