[928uk] No start.

[MARTIN PRUCE]

Thank you so much for all your advice and information guys. This truly is an enthusiasts site one in which I am in awe with the information you have. But I think I may have to advertise the car for sale as this was my daily runner and I will need something once my furlough ends. I don’t think I can face taking the manifold, injectors etc of again  to have the nightmare of replacing the cps. Maybe not so bad if I could do it in a garage but on the drive, not so appealing.

I will see if I can get a hold of the relay for the ezk and try that first...you never know..
Thanks again for taking the time to share your knowledge.

Kind regards.
Martin.

I think it’s not the body of the CPS that gets stuck, but the rubber o-ring nearer the flywheel end. If you can get it moving upwards, it will then jam if it gets even slightly ‘cocked’, so the trick is a straight up pull.

To get things looser what I did was take out the bolt (that should be no problem), then rotate the CPS back and forth to free things up. What works for this is an open end spanner to grab sensor body (don’t recall what size), and then a short extension at the ring end to act as a handle. The CPS will gradually rotate more and more in each direction.

I couldn’t get it to come up using thick wire wrapped around. But I had intake off so what worked really well was a ball joint splitter under the CPS (rotated so that handle of splitter pointed to front of car), and then I had loads of room to bang it with hammer and drive the CPS straight up. Came out in seconds. Realise you don’t have intake off so this is useless, but gives you some idea of how tough it can be. I’m pretty sure the CPS in my MY91 was original and it was fully working, but I took advantage of intake being off to replace it. If it fails then I also know the hole in bell housing has been cleaned out and I used a smear of anti-seize, so getting it out should be relatively easy.
