Title: mv6 failing to start - any ideas?
Post by: DJ_Brian on 13 June 2007, 18:31:23

One of those weeks!  A few nights ago, my mv6 3.2 started after cranking for about 5 secs, it normally fires up immediately.  I drove 50 miles, parked, an hour later it would not start.  Waited an hour, it fired up. :-?

Next day, car was fine.  Today, drove an hour, parked at work for 7hrs, car will not start. :'(

Any ideas before I call out the RAC?

You need to read the fault codes... I suspect crank sensor failing...

Yep, basics first, do the electrics work - such as windows. Do you have dash lights?

Try to jump start it to eliminate the first obvious problem - the battery.

After this i suspect the usual suspect  ::)

If the engine is cranking fast - the battery won't be at fault...

UPDATE!!!!

Well, our friendly RAC man has been and immediately suspects the crank sensor.  He did pull it out and clean it, but to no avail....Luckily this time the fault has gone hard, so I'm waiting for a shovel to recover the car back to my garage.

Thanks for the advice, this is a great place :y

Ha ha like it......as if cleaning a hall sensor will do owt!

Its the cable that fails due to heat anyway.....

Bless. In the words of Monty Python, an act of the purest optimism....

Guess I'd better get a spare for the tool kit if these are failing on 3.2s now...

Was that a genuine VX one or did you find an alternative source for a 3.2 one? I've seen them on Ebay but have heard there are various different connectors?

genuine Vx - there's only one for the 2.6 & 3.2, it's the same as the one fitted to the later 3.0's. P/N is 90540743, cost about £42 - but a worthwhile investment and will save waiting for one to arrive when (not if !!!) it fails ...

OK. Thanks for that. Will get one for the tool kit, and maybe a HBV too!
