My car's never been happy doing hot starts - it always required a bit more turning over before it would catch. Recently it has been worse. After a long drive a few days ago I got back in it, and it would turn over but not catch. I checked everything, and came back to it 30 minutes later and it started perfectly.
Today it happened again - it started perfectly this morning, I drove 20 minutes to the shops, and when I came out a short time later it would turn over but not catch. I left it for 30 minutes again but still no go. I've got 3 days of AA cover left so I thought I'd get my money's worth. He turns up after an hour, tries it and it cranks but won't catch. Checks all the stuff I already checked, and can't find anything wrong. I tell him I suspect the NTC sensor, and if he has a multimeter we can check the readings with the Bentley. He has a go at it, and gets nothing. No reading at all. Puts a new sort of attachment on the plug and gets nothing from that either.
Now I'm assuming that being an AA man he knows how to use a multimeter, because I'm not 100% sure that I do. So I'm guessing he did it right. What I'm wondering is, if an NTC sensor fails, could you get no reading at all? If so, that would presumably explain the hot start problem. And for people who have solved their hot start issues by changing the NTC sensor, where did you get one from?
