Engine cutting out

Engine Mechanical problem 4 cyl Front Wheel Drive Manual 96940 miles

I have just experience the fact that my car, shows the engine management light, and then the engine cuts out and stops. There is no power at all coming to the engine.
This has been checked by the AA on their computer, and it shows there are no faults found. After this has been re-set, the engine starts and goes for about another 30 miles, then the same thing happens again. There is sometimes a tinny sound coming from the engine, could this be the CAT System.
The fuel appears at times not to be coming through, and then the engine is flooded.
The engine revs. When started and running cold, are at 1000, however, when the engine is warm, the revs at running at 2000.
Couild someone please help me with this problem?
Thanks.

First, please understand, without a code, this is hard to diagnose from here. I have to ask a couple questions. First, when it happens, you said there is no power. Do you loose everything including horn, lights? Next, you mentioned it seems like there is no fuel and then too much flooding the engine. Have you removed the plugs to see them wet? Finally, when this happens, is it all at once the engine shuts down or does it seem to choke out, bog, miss. And is there ever any black or white smoke coming from the exhaust?

Let me know so I can start to eliminate some things.

Joe

PS: If I provide procedures for checking things, are you able to complete them?

Thanks for reply. Did not mean to be aggressive, just worried.
1, When the engine cuts out, I still have all the other items working, eg. Horn, etc.
2. It appears that no fuel is getting into the engine, and after attempting to start it, it appears to be flooding the system, and you can smell petrol strongly.
3. I have not removed the plugs to check them, not did the AA Engineer who came out to me.
4. The engine seems to start to cough, sorry to put it like this, but I can find no other way of explaining it.
The engine then seems to die a death, and the vehicle coasts to a stop.
5. I have never noticed what colour, if any, smoke is coming from the exhaust.
6. At times there appears to be a rattling noise from the engine, just like money in a tin can, perhaps this will help you.
If you provide me with some procedures for checking, I can get my friendly mechanic to try them for me.
Hope this clarifies the matter somewhat.
Hope you can help, getting desperate.
Thanks.

Hi we have exactly, or very similar problem. I am a motor mechanic from old days so not quite up with computers in cars. If we travel at no more than 2800rpm we can hold off the problem a bit longer. As Kath says the vehicle begins by just "dragging" a bit, this takes a bit of intuition as my wife doesn't notice this part but having experience and a lot of driving history I notice, almost like a lean mix in old type vehicle, then the miss comes on suddenly, very aggressive like more than 1 cylinder, rev counter dancing down to 0, and finally dead engine. It does not seem fuel related unless the lack of fuel also cuts the rev counter out which doesn't seem logical. Any aggressive driving brings it on sooner. I have been very suspicious of the crankshaft sensor but without the experience have not thrown it yet. Spent quite a bit of cash on diagnostic equipment but they all show no fault codes, which the mechs assure me would read up crank sensor fault if there was one. Any help would be good seeing it renders the wee machine dangerous in traffic seeing it can die at any moment. Cheers Clem

Hello,

Your mechanics are wrong about the crankshaft angle sensor giving a code when it goes out. This is the first sensor we change when these kinds of problems occur.

Here is a guide that will give you an idea on what you are in for when changing the sensor.

Here is a diagram of what it is like on your car (below)

Please let us know what happens.

Cheers, Ken
