DDK - Die Deutschen Klassiker

Yep I reckon I could have lifted the car with it!

Anyway back to re-inserting the intakes and then resumption of diagnostics.

I may end up calling the AA again…..

Thanks Gary. OK I got to look properly at the plug and the socket. Fortunately/unfortunately both are perfect https://uploads.tapatalk-cdn.com/20240422/203ffd08ee328f928c436cbd8bf57e78.jpg I took them both apart took out the connectors and wiggled them about and they are all solid as a rock. Well I’...

Well that was a bit of a saga


Having lunch now but I now have good access to the plug and the socket

No harm in asking The tank is fairly low but there is fuel there - there was fuel pressure built up in the fuel filter when I loosened the fittings the fuel pump is running - I can hear it each time I believe power is getting to the ECU but haven’t tested that - I did test that power was getting fro...

Then I did the tests in the Bentley manual on the two crank sensors - position sensor and speed sensor. Pins 1-2 are meant to give 960 ohms resistant and 1-3 and 2-3 area meant to give over 100K 1-2 tested fine on both plugs and came out around the 960 mark 1-3 and 2-3 - I couldn’t get a reading no ...

OK I’ve tried that now I first did the tests on the DME relay and they seem to be working fine - pin 87 is charged up with 12 volts. Then I went to do your test on the injector plug. Tested the first pin and got 12 volts. tested the second pin and got 12 volts again! Not sure what that means. I trie...

Fantastic - thanks Bruce

Thanks Bruce that’s really helpful and cleared up what the 2 is What’s occurred to me overnight is that I checked the socket in the engine bay and it looked fine and clicked back together. However I never looked inside the male plug that was attached to the intake stuff So today the plan of action i...

I’m confident there is no loctite on the tip of the cts sensor but in any event that isn’t touching anything - it doesn’t bottom out in the hole

But anyway I don’t think the cts would stop it from starting - I’ve had a faulty cts sensor before and it started fine but ran badly

Thanks Wayne and Jon and Gary OK I’m trying to read this wiring diagram to help me work out how to test that plug wiring works https://ensaster.com/pics/pelican/diagrams/88-porsche-911-engine-wiring-diagram.pdf The top one is black and white and the bottom is the same one in colour. Looking at the w...

I’ll try a spark plug tomorrow, but given how much it has been cranking there is no smell of fuel at all.

It won’t be easy to check out that plug but I’ll see what I can do

I’ll also see what I can do about running tests on the sensors

It’s a possibility but I did check it thoroughly when the engine was out and it seemed fine - everything clicked back together

OK I swapped out the DME relay for the one in the glove compartment but no joy - exactly the same (great cranking but nothing firing) I don’t know the one in the glovebox is any good - are there tests I can do with a multimeter to confirm that? So I guess if it’s not that then it would be most likel...

No I haven’t touched that Jon - good call - I think I’ve got a spare one in the glovebox. I’m at parents house for a birthday now so will try that when I get back - the DME relay is the one under the passenger seat isn’t it? From memory when the engine wasn’t earthed there was mad clicking which cou...

Yes that’s plugged in - is that the fairly big one with I think 4 connectors in it?
