Sounds to me like a possible crank sensor failure or a sticking starter motor solenoid.

Has the Engine Management Light come on at any point maybe its worth reading the codes.

The paperclip test is in the guide section.  see below

don't think starter solenoid. Solenoid problems would mean no turning over or starter not engaging. Crank sensor is a possiblilty though.

would the crank shaft sensor stop the spark then, when the car started the engine management light went out as normal.

Crank sensor from what I have read in the past has been intermittent the best way is to run the paperclip test just in case any codes are present then go from there.

Hi Nick, I'm no expert but I've had crank case sensor pack up on mine and symptoms are exactly the same. Sometimes engine used to turn over without firing, try again later and starts ok. Try push or tow starting it (if it's a manual) and chances are you'll find it'll fire up easily. Shouldn't be too costly to get the sensor replaced.

My initial reaction is crank sensor.  Do the paperclip test to see what ECU thinks is wrong...

did in read on here somewhere that (because of a starting problem) if you disconnect the crank sensor at the elec connection it will then start the car but be in limp mode? if so it may be a way to confirm the c/s is at fault? and also do the paperclip test to double check!! :-/

Most of these cars won't run at all without crank sensor.  2.2 petrol seems to be the exception...

Agree with TB....2.0/2.5/3.0 wont start with the crank sensor disconnected......however a 2.2 definately will....anyone with a 2.6/3.2 upto disconnecting the crank sensor to see if it will start? To prove if its only a 2.2 will start without a crank sensor? It might take upto about 5 secs of cranking to start tho.....

You've described the exact symptoms I had... and it was the crank sensor.

£50 for the sensor and 30mins to fix (as long as you can find the plug, it's a bit fiddly to get at). It may take longer if for example the wiper arms won't come off.

According to my sources (well I looked it up on the Internet...) the Crank Sensor for the 3.0L was different than that of the 2.5L, but it is the same one later used on both the 2.6L and 3.2L.

Crank Sensor 2.6/3.0/3.2 Vx P/N 90540743:



Crank Sensor 2.5 Vx P/N 90492006:



Though strangely they both look the same....
