Question on Fuel Pump and Filter Replacement

Hi Nick. thanks to you and this guide I have successfully replaced petrol pump and grommets in tappet cover on my 2004 cooper. only problem now is that it does NOT want to start on the first turn. In the morning at 1st start it only swings, on 2nd attempt it starts and idles for half a second and dies off, on 3rd attempt it starts and idles for 1 second and dies off. on 4th attempt it finally starts but on a high rev and then settles down to normal revs after about 4 seconds. I have replaced plugs and checked that all fuses are dry thought it could be an electrical problem. but once vehicle is warmed up then it starts on the first turn. not sure what to do now??? please help

I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume, quality and engine compression. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.
