180 starting issues

[glane85]

No idea what the problem is, but from what I've read about the KV6 if the ECU sees any fault from the crank sensor it prevents the car from firing. That info was from a Freelander KV6 manual, but I imagine it is the same for any KV6 regardless of which car it is mounted in. I think from memory, if it detects a fault with the crank sensor while the engine is running, the ECU also shuts the engine down too. Could be a problem with teh sensor itself, or the wiring/connection to the sensor? There have been a few threads in the past on several MG sites, where people have said "car won't start" or "car cut out", and advice has been to clean the crank sensor. Apparently it can become dirty within the housing and a good clean can help. No experience of this personally, but just relaying info that may help...assuming it is true, of course!

Have you checked that the fuel cut off switch behind the centre console hasn't been tripped ?

That's another thing I was think pete.don't know how it would have got tripped but another thing to look at.just trying to list as many ways of attacking as I can won't get to it until the weekend as its in the garage which has a slope in to it so if I can't get it started I can't get it back in there.

Couldn't you take the crank sensor out of your good car and try it in this one ... ?

Was thinking that Dan but it's in an area of a place to get I to and don't want to risk two dead cars.

My bad - thought the sensor you were on about was the one on the front of the engine block. My Mk1 had a starting problem and when I got one of them for £10 second hand it was sorted. Maybe that sensor then mate - I thought it was the crank or maybe camshaft sensor ... ?

It's certainly easy enough to swap out - even I did it!
