Condenser probs? Cut out when warm, OK when cool, and v high temp guage reading

snipped from a previous thread started by Paul :

Traveling along > the A47 at 50 and she coughed, I thought " oh thats a bit strange". > Went a bit further and she coughed again. Got to within 2 miles of > the house and the engine dies. Wont restart. Get out and disconnect > fuel hose and check fuel pump. OK. Check spark at HT lead. No spark. > Disconnect LT leads from coil and Dizzy. All seem Ok. Reconnect and > she fires up. Get another mile down the road and she conks out again. > Again I get out and diconnect and reconnect LT leads. She fires up > again. Dies about another 200 yards down the road. > > I think the condenser has popped. I'm going to change the Coil, > condenser and HT leads tonight and see what happens. > > Any one else think any different ? > > It may be unrelated, but the temperature guage goes off the scale yet > the fuel sender works and the temperature at the top of the rad reads > about 78 degrees C. > > Cheers

And a reply to this:

Have just replaced the condenser on my car. It stopped working >whenever it got warm. If you let it cool down for a bit, the car

would

start again. >I thought it was the coil at first, but replacing that caused the car >to stop working when it was cold too!

I'm having precisely the same problems, and thought they were unrelated. Can anyone offer an update, or further advice? If it's intermittent, that suggests maybe heat related, or physical (loose) connection??

Is the stop a complete cut out or a sudden power loss followed by stalling?

I only ask because the 101 problem I had lately turned out to be an inlet manifold leak - air getting into the engine when it was hot and under load. After a short rest it would be OK for a short distance then die again.

It's the latter, definitely. It's complicated in that I have a LPG / Petrol dual fuel, and total power loss is only when in LPG. I guess that suggests an air intake problem with the gas bits?

It also fails to start when warm sometimes, but that's in both LPG or petrol. I dont think that's air/fuel though, more likely electric or starter, as there is no noise/movement from the starter. A roll start when possible generally succeeds, but so does leaving to cool. Hand cranking doesnt usually, but that might be my technique!

Thinking about it, it seems to be two unrelated problems that are confusing me.

That can often be the way. The 101 starter decided to pack up just when I needed to restart every 10 minutes!

If it is temperature related then you need to think about what changes when it is warm. Most obvious is the geometry around the various seals and gaskets, which could cause a leak. Less obvious is that electrical connectors and switches could play up, or it could even just be vibration rather than temperature.

In some ways you are lucky to have LPG and petrol. Run it on petrol only for a couple of days. If you have no problems then you can be virtually certain the problem is in the LPG. Do you have a clever variable advance thingy in your dizzy to advance when on LPG - that could be dicky?

Also LPG is more susceptible to poor ignition - any backfires?
