Just a thought.... If you start it up and then keep turning the key on and off quickly, will it keep running? Hi. Tried and tried to keep it running by flicking the ignition on and off to no avail. It will keep running if i flick the ignition inside the 2 seconds but after that it dies as before. Immobiliser? |

Immobiliser? just click on the link I put up for you Hi Stuart, Been there and done that. Bought an ECU etc. Swapped it all out. Made no difference. Im considering getting an ME221 ECU. Whats are the odds it will work ok then? |

I read that you had tried another ecu and key. But did you swap the key reader around the ign barrel, it's connector and the immob unit and check connectivity of the associated cables and grounds?
If you have a spark after it cuts out and the pump is still running causing fuel to squirt from the injectors then it has to run. Well that is assuming the fuel pipes are the right way around i.e pump centre pipe to the opposite end of fuel rail to the regulator?
I doubt it will be an air leak as a missed off vacuum pipe doesn't usually kill it all together, have a good look around the plenum though, you never know.

I am aware of the key sensor and little.black box. Swapped out everything. The pump may be running but it does seem that when the engine dies there is no fuel getting through. Wish someone new what the immobiliser does to stop the engine. |

Have you got a 3 pin coil or 4 pin?

Wish someone new what the immobiliser does to stop the engine. the immob cuts spark, fuel cuts if ecu senors no engine rotation and assumes the car is in a ditch. Try overriding pump relay or stick a pos on the pump, careful though, sparks and petrol should only be mixed in the combustion chamber |

I know for sure that the spark keeps going and the pump also. I can hear the pump run on after the engine dies. I have also jumped fd and ground to make sure. So it can't the immobiliser if the spark continues. Why would the injectors stop? |

Been looking at the wiring diagram and I wondering if there's a wiring fault between afm and ecu. Not 100% sure but looks if ecu doesn't see air flow it stops the injectors.

the 1.6 MK1 has a flap in the AFM so without air flow the pump cuts off. This feature is to cut fuel in the event of an accident. The same applies to the later cars but is done electronically not via the troublesome 1.6 flapper.
As you say you have tried another AFM you may be getting close.

Hi Double
You say you go to Nuneaton from Norfolk a few times a month. I live near Spalding, a bit of a detour but if it helps!, so if you need a loan of a part for a few weeks or so to save buying bits you might not need I might be able to help you out.
I don't look at the forum very often but I'm on the facebook page if you want to get in touch and arrange something.
Good luck
Jason

How are you getting on@doubletrouble? Issue still occurring for you?
I’ve not pulled the trigger but ME have 10% off on the ME221 at the moment for Black Friday so possibly pull the trigger. I think my issue is immobiliser and I believe the me221 will get around that
