Thanks Nige. Are you around tomorrow? An extra brain and pair of hands would be great.

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod

Thanks for all those comments and links guys I dont know what the immobiliser immobilises. My system uses the original crank sensors and neither have been touched throughout the recent work. Those posts are interesting. The cylinder head sensor one was surprising. I’ve read up on using loctite on ea...

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod

OK so plan (c?) is this I’ve now fitted the anti-roll bar and the rear wheels and lowered it off the lift. I’m going to put the engine stand and engine hoist away and then phone the AA to say it’s not starting (I do pay for homestart) - I’m tied up tomorrow but aim to do it on Wednesday I’ll let the...

1987 3.2 Carrera Backdate project - Sladeys hotrod

Just throwing ideas out there… What actually makes the spark on your car? I know you have the CANEM ecu for the fuel but where does the spark come from? Pixies. Or It’s the Canems DIS ignition conversion kit - does away with the dizzy. I fitted a spark detector inline with the plug on number 4 cyli...

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod

Just thinking out loud here, I see in the pictures you have a TOAD alarm, so is the immobiliser shot, or not actually working, or did you remove all that gubbins in the rebuild process? Although the toad is quite old it’s always worked well - it disarms and arms fine. I had it installed about 15 ye...

1987 3.2 Carrera Backdate project - Sladeys hotrod

Is the fuel pump still running whilst cranking? Can hear it ignition on, but not when the starter is going. My hearing’s not great so I can’t be sure. There was pressure in the fuel system but I guess that could have come from the priming. The DME relay also controls the fuel pump. I tested that an...

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod

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…..

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod

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’...

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod

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...

Re: 1987 3.2 Carrera Backdate project - Sladeys hotrod

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 ...

1987 3.2 Carrera Backdate project - Sladeys hotrod

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...
