I would favour injectors for this problem.Has the filter been changed?hth

Hello

I hope your problem has been sorted by now, but I've recently been through a similar thing with my 58 Cooper D.

It was at the local garage for four entire weeks before they managed to get to the bottom of the problem and fix it. The fault codes were showing a problem with the crank shaft sensor, so that was replaced. When that didn't fix it, they replaced the cam shaft sensor, and that didn't fix it either. They then consulted the MINI garage, who said that it was the crank shaft sensor, and they should have used an 'official' MINI one. They tried that, and it was no better.

Through a long process of trial-and-error, they established that there was indeed air in the fuel line. So they bled the air out, and all was well until they left it to stand for a few hours, and air crept back in.

Excuse my lack of knowledge and poor terminology, but here's the thing: There's a valve on the return of the fuel line (or possibly a return valve on the fuel line) to which there is an electrical connection. Unplugging that connection solved the problem, the air stopped coming in, and the car started immediately and consistently.

For a more permanent solution, the garage ordered and fitted a replacement valve.

But it took them a full 4 weeks to get there, as all the diagnostic codes ever came up with was a faulty crank shaft sensor!

The car has been back with me for 3 days now, and has thus far started fine every time.

I hope you're problem is now solved, too.
