Hello and Welcome to justanswer..

Can I just ask - did the car break down / stop while driving ? or have you come to it and found it like that ?

Is there any background / history to this - the more you can tell me , the better...

Is the engine cranking speed normal - or is it slow / sluggish or unusually fast?

What mileage do you have ?

Have you done anything so far - replaced any parts and so on?

Hello again -

Ok - thank you ...

Right well - the biggest suspect here would be the crank shaft sensor then but you need to check some basics first - ie, check for a spark at the plugs and see if you have fuel up to the engine -and then check if its being injected.

The crank sensor failing will cause a non start as its the main trigger for fuel injection -and ignition..so if you find you have neither, thats usually whats wrong.

If you find you have spark at the plugs - then likely you have no fuel up - to the engine. Check then for that - Usual cause then would be fuel relay / fuel cut off - fuel pump - or even just a clogged filter.

These are the common things - things that need checking through

OR - if you have access to a fault code reader - you can plug into the cars diagnostic socket - as you have that fault message on - there will be fault codes logged in the ecu - and that then will tell you whats wrong that way..

So those are the ways forward on this one Scott to get it sorted for you ;)

Im very pleased to have helped you - Let me know if I can help anymore...
