Thread: V8 D1 Cuts out intermittently

It"s most likely the ignition, check all the electrical connectors around the ignition coil and module, make sure they are all on tightly.

When you fitted the ignition module did you also smear the heat dissipating compound onto the back? They last longer with this applied (or so I'm told) which is why most manufacturers provide a small sachet with each module when you buy it.

Check your coil connections, and others too.
I had a similar problem, and it ended up being one of the terminal connectors loose and in basics, disconnecting itself. Sometimes it would right itself quickly, other times it'd frustrate the hell out of me.

No, I didn't. I will get some and add it, I suppose. At $150 I would like it to last. But.. it's beside the coil and next to the radiator at the front of the engine, in the airflow I guess. I would hope that it doesn't get that hot.

Thanks for the heads up.

Thanks Chops, and bee-utey too. Connections look OK, but... there was an earthing strap floating around! The bundle coming from the dizzy to the coil and ignition module inclues an earthing strap, has a bolt in it but not screwed into anything - and I can't immediately see a threaded hole it's supposed to live in. Must be somewhere in the vicinity of the jack/chock/power steering reservoir. In the absence of info about the right hole I'll make my own - but maybe someone can look under their late D1 bonnet?

I could find nothing that looked like a loose connection, and the earthing strap was clearly nothing to do with the problem - at least earthing it didn't fix the problem. So I replaced the 3 month old ignition module. We now have an immediate fix, but I suppose it remains to be seen whether we have a long term solution.

The good news is the price. The previous one was Lucas from Range Rov, and cost me $110. The new one was $55 + $9 postage from British4wd. Ordered on Saturday, arrived Tuesday.

So now I have two supposedly dud modules - the Lucas and the original. I'd like to get them tested - anyone know how to get that done?

I suggest you bin the old ones, OEM and aftermarket ignition modules have a habit of dropping dead at inconvenient moments. I developed a Bosch alternative which is considerably more reliable.

I was more interested in confirming that they are stuffed than reusing. I think of solid state devices as being inherently reliable (not talking cars), so I found it strange that a new one would fail after 3 months. However, having read the older posts by you and others I understand that this is not an uncommon problem with Rovers, and you have found that your Bosch alternative fixes it. Very enterprising btw, and great piccies, well explained.

So, you think that next time this thing fails I should convert to a s/h Bosch?

I love the car, but other electronic bits are problems. The cruise control is cactus and new ones appear not to be available. Range Rov supplied and fitted a s/h ecu which worked for six months. And the electric rear windows mostly don't work, obviously an ecu issue. I'll search this site..
