I had it a few times in the last couple of weeks and sort of managed to fix it by locking the car and unlocking again with the remote. Here is what happens ;
THE CAR IS A 2003 MINI COOPER S with 103k MILES ON THE CLOCK
Turn the key over ,you dont hear the fuel pump priming noise ,turn the key further to start up . It starts up and revs around 500 rpm for a few seconds and dies slowly. Once the engine dies you hear a noise similar to the radiator fan but its coming from around the exhaust manifold area and it keeps going until you turn the ignition back off .
Like I mentioned ,I managed to get it to run by locking unlocking the car a few times which made me think it was some sort of immobiliser/anti theft system issue . However when it happened again yesterday ,no amount of locking and unlocking fixed it. Seeing the pump is not priming at all ,I pulled out the back seat to access the fuel pump and filter covers .
All I have done was to give both covers a good hit using my hand and turn the ignition on and I could hear the pump priming again then the car starts and runs perfectly fine as it does .
Would it be safe to say the fuel pump is on its way out and causing an intermittent problem like this ? Also what are the chances of a never replaced fuel filter stopping the fuel pump from starting at times ??
Any help much appreciated
