How much fuel in it?

If more than a 1/4, then almost certainly crank sensor  :y

Pedal/Paper clip it and report back :y

My wife had this problem years ago on her ex-police 3.2. A change of battery cured the fault, I could not explain why.

Unless it's perfectly level below a 1/4, once it doesn't start, it won't without a few gallons in it... You might get lucky by levelling it.

Estates suffer more from this and can take a 4 gallon top up before starting.

Fuel filter, whilst a service item, won't solve the problem.

I wouldn't change anything until you've read the codes. Whilst the fuel filter might have crud blocking it's probably the least likely cause of your problems. Get the codes first and then decide what to do.

Snap-on is professional stuff so I would hope that your Snap-on reader would at least read and reset any engine fault codes. Might need a software update?

Saloons don't really suffer this, even with weak pumps. It seems unique to the Estates.

I don't know much but I believe code 31 is normal when engine isn't running.
Someone with more knowledge will be along soon.
