So now I need your kind folks help. Timing belt looked fine around the bottom cog of the crankshaft. As previously said, I took the pulley off the crankshaft, cleaned all the bits of aux belt that had got in there. Cleaned the crank sensor, put that back on together with the pulley. I've got a cheap ob2 reader, which said no codes, but did a clear anyway. Reconnected battery obviously, and tried to start. Turned over but not starting. For info, I used the old timers belt method to get the crankshaft pulley nut undone, as I don't have the kit, pins and flywheel locker. Help please. Where do I go next ? |

So you can see why the old aux belt was shredding. The tensioner was starting to fall apart. Some of that shredded belt got behind the crankshaft pulley. I'm an old git, and I've heard pistons meeting valves before. No decernable noise when turning over, or would there be ? Help, I'm gonna cry. |

I may be wrong but I thought that if the crank sensor is faulty then the engine wont even turn over.

Not a clue Jules. Hoping I can get some advice on here. I am wondering if it could be that there are some codes that are stopping the car from starting but allowing it to turn over. perhaps the cheap obd11 reader that I have is not good enough. At the moment I can't go any further until I get some advice. |

You must lock the flywheel and cam pulley with timing pins before removing and refitting the crank pulley, as the cam pulley behind the crank pulley isn't locked with a key in a fixed location, but is held in correct timing by the crush of the crank pulley bolt.

Thanks for coming back to me Nodge. Because I didn't remove the timing belt, I can't have altered the timing can I ? The cam and crankshaft have always remained connected throughout what I have done today, have they not ? That does not mean that the timing belt has not jumped a couple of notches when the problem first happened. Really appreciate you input and help. |

A hard battery reset might do the trick after changing the sensor. Basically disconnecting pos and neg and touching together for about 30 seconds to a minute, of course, without contact to the physical battery or vehicle body. Neg is ground. |

Thanks Motionink. I will get a new sensor GSF about £25 in the morning, and try the hard reset. Thanks |

That CPS looks pretty ****** up to me! When you crank the engine you should see about 200rpm on the tacho, if it's working! The CPS rarely sets codes in my experience, it should fire right up once you change it, hopefully. This is what it's supposed to look like, look how yours is damaged in comparison.
