Thanks I will look at the wiring as soon as I can. The car is at least driveable now, so that it can get to a garage to check for codes. What is odd is that with the MAP sensor unplugged the car runs and drives, its likely to stall when you take your foot off the the gas to quick. BUT the engine warning light is on. If you plug the MAP in you'll be lucky if it runs for 30s but there are no warning lights on the dash.

Hi All, So I put the new MAP sensor in place, and started up, and the same issue presents its self, un plug the MAP sensor and its all good again. So this leads me to think that there is either a wiring issue - or a problem with the ECU itself? So the other question is how safe is it to drive with out the map sensor - my understanding is this is helping the ECU determine when to spark, so it may be a little rough without it? Thanks John

OK, thanks will take a look and see what I can find.

So got a part number will order a new map sensor and hopefully all will be good. Thanks for the pointers and ideas!

Well, I have just unplugged the MAP sensor and the car starts, idles and revs - so looks like that's the culprit.

I don't have a means to check the codes here - I may be able to get hold of someone who can. In terms of the butterfly its mostly closed through out until it really starts coughing, then it opens fully just before dying. I have checked that the spark plugs are sparking - I will find out if anyone has mentioned the MAP sensor in looking into this.

I would have to ask the garage and my brother (who's car this is) about before the timing chain was replaced. I have just carried a compression test out, and all are reading 12 - 12.5 bars.

Hi, I have been looking through the forums to try and find any advice, or people with a similar issue. I have found various threads but nothing that seemed to quite fit this. Engine is a 1.2 BME code 2006 Essentially the car starts, runs for up to 30s and the dies a lumpy death. This is with no foot on the accelerator and just from a turn key start. If you put your foot on the accelerator the engine will pickup up briefly, but will then return to the same lumpy death. There are no warning lights on the dash - all seems to be normal up until the point the car dies. The code issue appears to point to a crank shaft sensor. The car has been in to the electricians, they have changed various parts - cranks, cam, lamba, oxygen sensor etc., Different throttle body, different ecu. - nothing has made any difference. They decided that the issue must be the timing chain and that something is out there. The timing chain has now been done - thanks to the posts on this forum for some great pointers in that process. Nothing seems to have helped. I have put a link in to a video of the engine starting, and then dying in case that helps: https://photos.app.goo.gl/rowmoTdZaW4mdCnD7 Thanks John
