Maybe I was unclear but I was referring more to the solution suggested than the problem that guy had:

"...the problem of starting on the second try is normally because the fuel pressure has bled off the injector rail while the car sat. The check valve (normally in the outlet of the fuel pump) is supposed to keep the pressure up for many days but a leaky check valve or dripping injector can bleed off the pressure in minutes. When you crank the first time the fuel pump runs to restore the pressure, and when you crank again it is ready to run. I'm not familiar with the Mazda, but most cars will also start on the first crank if the ignition is left in the "on" position for a few seconds (like 2-4 seconds) before cranking if the pressure has bled off."

I am going to monitor times between the failures.It seems that issue happens only if some time has passed that correlates with the explanation above.Also I will try to leave ignition in 'on' position as suggested above first thing in the morning.

Ok mate fair enough but that sound in your video is the sound of the starter motor spinning but not engaging with the flywheel.

If it was to do with fuel pressure the stater motor would still have engaged and turned the engine over. But it didn't.

As above

Also check the wiring to the starter, check the earth points for corrosion on the solenoid but its sounds like how mine did last year which at the time I paid £70 for a new remanufactured one from Bosch.

Thank you Leon27,

 Do you remember where did you get it from?

EuroCarParts. I work in the trade so get a discount, if you have a mechanic mate I'm sure they should be able to arrange a similar deal :) Think as forum members we get some money off too... This might help
