Thanks

Here's bee utey's Bosch amp conversion: http://www.aulro.com/afvb/technical-...sch-024-a.html

And for the dizzy cap, it must be a Lucas one, not aftermarket. Same goes for the rotor button. The aftermarket ones crap out pretty quickly.

Must learn to type faster than you Bee Utey!

Funny you're talking about blue dissy caps, yesterday a customer handed me one in a box (says Made in Italy) and told me to fit it. It's so loose on the dissy body I wouldn't trust it to not catch the rotor button. So I polished up his original black Lucas cap and put it back on.

As for the OP the coil lead could have fried, causing excess voltages reverberating around and breaking down the coil and the Lucas amplifier. Also the amount of loose connectors I see around the coils on LR's its a wonder they ever keep running. Carefully squeeze any crimp connector to the coil and make sure they go on with a little force. This makes better metal to metal contact than loose dirty old connectors in crumbling nylon sleeves.

Yep my blue cap is loose, where the clips clip on it's a bigger space by about 5mm (if that makes sense) & allows cap to be twisted, by hand anyway

Thanks I will double check for loose connections although they seemed ok when I put the ignition module in - the coil lead I will check as I remember when I changed all of the leads and disy cap, the new coil lead was too short and the mechanic put a second hand coil lead on instead.

When you say the Lucas amplifier is this just another name for the ignition module??.

Also the ignition module that the LR mechanic sent to me was a "Bearmach" brand & the box says LR parts & accessories.

Whats the chances that it could be the coil, it has a Bosch one in it, not sure what type as the label has worn off.

Anyone know the code/id number for the 1994 3.9 v8i

Well I put a new bosch coil in today, no improvement at all.

The done list so far:

1/ Plugs - leads - Dizzy cap - rotor button
2/ Fuel pump - fuel filter.
3/ Cleaned stepper motor - cleaned MAF sensor
4/ Ignition module
5/ Ignition coil
6/ Checked/tightened all relevant connectors/leads

Got in touch with a mobile landrover mechanic today but he can't come till the 29th April, explained every thing to him and he reckons that it may be the temp sensor.

Would he be talking about the Fuel Temp Sensor or Water Temp Sensor?????

Also what is this little rascal (see att pic) it is located near the ignition module and connects to the coil - the markings read AMPOHN - 1uF159V (or similar).

RF suppressor to stop ignition noise in Radio.

Many Thanks

ps; At this stage I have decided to get it towed to my Landy guy ($75) on Monday and let them sort it out.

Defeated I am.

The pickup coil inside the distributor can also cause the sudden stop, and restart as it cools momentarily.

Thanks for the suggestion, but I am now at the stage where it is getting to expensive to continue buying and replacing parts in hope and not getting any results.

For example I rang up to get a price on a fuel temp sensor and was quoted over $300, now if I knew that would fix the problem then so be it but it is way to expensive just to eliminate another possible cause, so it is time to leave this one to the experts.
