8000 rpm/300 bhp 3.2 rebuild

[911hillclimber]

Hope so or I'm in the dog house along side the hedgehog hotel.
But, will any work?

Soon time to talk to the rolling road man.

[sladey]

Good luck with that Graham - fingers crossed you hit your target

[911hillclimber]

Thank you for the wishes, Can't help feeling pensive about it all.
I've asked Clewett for a safe start advance spec for the first attempt, but also how to immobilise the controller while cranking the engine to get oil up to pressure without all those plugs sparking away.

Will be chatting this through with the rolling road man too next week.

[DustyM]

Those leads look super neat Graham. Regarding cranking for oil pressure, it's probably more important to immobilise the fuel, the sparks won't do any harm, but you don't want cylinders full of unburnt fuel on first fire up.

[PeterK]

I did my oil pressure build up cranking without plugs, to reduce the initial load on the bearings. If they’re on the bench, they are unlikely to fire

[911hillclimber]

Just had a reply from Clewett.
Richard C has told me how to isolate the unit to allow plugs out oil pressure build.
No fuel is easy...
I don't want billions of volts jumping out to get me out of this snakes nest!
He has suggested a safe start spec for the advance curve points, so what can possibly go wrong?

Save me from wiring!
At very long last got to the end of all the wiring on this simple car. Takes ages and ages to do.

The XDi controller is wired and in place, about the driest space I can imaging in this far from sealed car.
Getting the pins into the large multi wire block was a real pain all refusing to simply push home. Had to open the whole connector up and do them. Hate it.

Made a splash shield in ABS sheet velco'd to the unit. The unit is a heat sink, so air much freely pass around the exterior.

The controller has to get to ground, power is needed (3 power lines) so they have to be 'enabled' only when the full ignition /fuel pump circuit is live. The kill toggle switch then shuts off power to the ignition and fuel simultaneously. They have to be individually fused too.
All the gauges have to get 12V prior to that status, but all done finally.

Put 12 litres of Shell's best oil into the engine...
Put a refreshed mega red-top racing battery int the car, and connected it up....
Went to remove the top set of plugs. Plug spanner too short, so mad one the correct length...
Pulled the 3 power leads to the XDi, no petrol in the car deliberately....just to ensure it would not start!

Turned the electrics on and pressed the starter motor. All churned over for 30 seconds and got 3 bar oil pressure at cranking speed.

Put all6 top plugs back in with my new plug spanner and nipped them up.

Cranked the engine over again for a few seconds, sure sound like a high compression engine!

No fuel means no first fire-up.
Planning to do that on Wednesday afternoon once i have the silencers on.
Too busy tomorrow and Wednesday morning.

So nearly there, no excuses left, just the

Moment of Truth.

Fingers crossed

good luck with the start up etc (If it was my vehicle , I would have a nice (possibly red ?) rubber boot over that positive connection on the kill switch ..... just takes a dropped spanner landing the wrong way, to have a diy welding course / exhibition )

3 bar pressure on the starter is good. You have to be happy with that

Good stuff - very exciting

[911hillclimber]

Well!

Engine will not start.

All turns over but not a pop, cough or fart.

According to the Diagnostics fault finder, the crank sensor is at fault (which would account for the total lack of life), but the resistance of the sensor is 616 Ohms, and the general figure for a good one is 620 Ohms, so nothing wrong there.

Have power where it should be and the right level, all grounds ok, all wires in the right holes in the ecu 23 pin connector.

Have emailed Clewett for guidance, have a clear morning tomorrow i hope to look again with fresh eyes and a reply from Clewett.



I hate car wiring.

Damp squid and all that, but will sort it tomorrow I hope.

[Cortina]

Did you actually check for a spark ? (I would guess you don't have one ..... but would be good to know !)

[911hillclimber]

No, I haven't as there is not a glimmer of life.
Richard Clewett is on the case.
The Ecuador has a status light, and should be solid or flashing green or red etc.
The status of this light changes so thus the definition of faults also change!

Hope the info I've just sent will help him guide me.
I think the sensor wire are far too close to the plug leads and coil pack and the noise is drowning out the crank sensor signals, and if this is so I have to re plug wire the whole engine...
Many days work.

[Cortina]

To quote "odd job" - go easy with the negative waves man .............. some simple shielding may be all that is required - if that's the issue (I think ..... note think , that is a semi intelligent possible solution ??)
