I've just figured out that the alarm stuff was caused by the recharged battery eventually going flat after all that cranking.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi All, I'm new here having just bought my first Porsche. Last week I decide to remove the gearbox to do some preventative work. This included replacement of the worn flywheel and clutch, together with IMS bearing, AOS and RMS replacement. Having put everything back together, I unplugged the DME to crank over and allow oil pressure to build. With the harness disconnected, it wouldn't even crank, so I plugged it back in and tried the methods of briefly starting and shutting off. The battery was near flat. It did turn the car over and it started for a second at which point I shut off. Since then the car will not start. I've charged the battery and checked the fuses. I can smell petrol when I it turn over which suggests the relay and pump are fine. Does it not also suggest the CPS is okay? There is no hint of it firing at all. Any suggestions? Thank you. Alan

POST 2 / ORIGINAL POSTEROriginal post

Just to add, I've looked at the car again: Tachometer does move when it turns over. I've replaced the DME relay. It's a UK car and so no clutch interlock switch. What's odd is twice now when I've been trying to start the car, the alarm suddenly goes off, windows roll half way down and no amount of pressing of the blipper seems to stop it for about 30 seconds.

POST 3 / ORIGINAL POSTEROriginal post

Well, I'm answering some of my own questions here. I've just figured out that the alarm stuff was caused by the recharged battery eventually going flat after all that cranking. Battery is on charge for the night and will try again tomorrow.

POST 4 / ORIGINAL POSTEROriginal post

Well, I charged the battery and tested the car this morning. Getting full voltage and staying above 10v when turning over. Still not firing. This time I noticed that the tach needle is NOT moving and I must have been mistaken in my earlier claim that it was moving. Wouldn't this point to a CPS problem? On the other hand, would a bad CPS allow fuel injectors to work (remember that I can smell fuel from the exhaust). Thank you!

POST 5 / ORIGINAL POSTEROriginal post

Okay, seems like I'm talking to myself here but this evening I hooked up my Durametric and got two fault codes: p1579 - CPS and P1571 - immobilizer When I tried logging actual values I could see that the CPS is registering a signal of about 130rpm when cranking, which sound right, so not sure why it is showing a fault. The immobilizer fault is a mystery to me. Any ideas?

POST 6Original post

So that CPS message is normally the connection to the CPS itself, or the ring gear on the flywheel being damaged, (or missing)

POST 8 / ORIGINAL POSTEROriginal post

Yes. the engine ground is connected and is something I didn't touch when I did the work.

POST 9Original post

If it were mine I would change the CPS. It is very easy to hit it when replacing the flywheel. You say you have a signal but it is giving a fault.

POST 10 / ORIGINAL POSTEROriginal post

Okay. Thanks for the input. I'll change the CPS and will report back.

POST 11 / ORIGINAL POSTEROriginal post

I've figured out the problem. The replacement flywheel had some bent teeth that the CPS is supposed to read from. Reference teeth have now been straightened and hoping to put the gearbox back in tonight. Thanks for the input.
