on Thursday last week it got really noisy so i bought a new pump and i am waiting for it to arrive. but today i noticed that the car smells like it is running rich when starting. would this have anything to do with the pump?
at the moment i have problems starting the car when its hot,the pump is on and off noisy but it will always get noisy on a long drive i assume when it gets hot.when its hot it has a rough idle when in gear or the aircon is on.when its cold it will start first time otherwise it will start on the 3rd try when pressing the accelerator. this problem has gone from being random to starting on 2nd try to being on the 3rd try now. could this be another issue like O2 sensor or temp sensor,MAF,fuel regulator or just the fuel pump. i dont have a diagnostics cable its something i need to get but about 2 months ago i put it on my brothers one when he came down from JHB and pulled misfire codes and crank sensor faults but that has been replaced since
