Engine Cutting Out

Thanks all for your feedback. I cleaned the contacts on the coil, and symptoms are gone, however one short drive is not really proof! I'll see how it goes and let you know. May need to dig deeper. Distributor module does make sense.

I hate intermittent faults!

Cheers.

Would a can of that "freeze spray" stuff assist with troubleshooting a heat-affected module, or is it bad to submit them to thermal shock like that?

Goodluck

Andrew,
Was this intermittent/random? How did you confirm that was the culprit? Trying to avoid buying replacement parts un necessarily!

Do you know if there is a way to test this? I think I'd need to buy the whole distributor as the module is integrated.
Thanks,
Scott.

I would be looking at the LPG side of things if you say you can see the LED's go out during the fault.

Today I had plenty of opportunities to further explore this fault. After performing flawlessly in yesterdays 35C+ heat, with AC on etc I was leaning away from something temperature related. However today was a disaster. About every 5km I had to give the disco a 'rest'. 5-10min was enough to get me another few km until I eventually made it home. The distance between 'rests' is definately getting shorter.

Therefore, combined with the fact that it cuts out just as often whether stationary, driving on smooth roads, or driving on rough gravel roads, I can pretty much rule out a simple loose/dirty wire or connection.

I paid some more attention to the LED's for the LPG, and noticed that they actually stay on for about 2 seconds after the engine looses power, which makes me wonder if that is in response to the real root cause, rather than directly related. Also had a LOT of backfiring today, which actually proved to be a lot more effective than the flashing hazard lights in getting people to go around. :p

So, given that ignition seems to cut first, followed shortly after by fuel, I'm leaning back towards the ignition module as the culprit. Roverparts have a replacement for $66 so I think its worth a shot unless anyone knows of a better alternative?

Cheers,
Scott.

The $66 option sounds reasonable IMO.
Make sure you use silicon grease under the module (it usually comes with it).

Replaced HT leads, plugs and relocated & replaced ignition module, which now sits over near the coil with an aluminium heatsink on it, rather than directly on the dizzy.

Thanks all for you help.
