I have just bought a cheap late 2003 Mazda 2 1.4 diesel with 100,000 miles which I believe is based on the Fiesta 1.4 TDCi engine. I have an issue where I start the car first thing in the morning and it runs for about 2 seconds. It then cuts out and will not start. If I prime the fuel using the hand primer in the engine bay I can see air bubbles moving in the clear fuel line. It will then start and run fine.

I think my mazda has had some aftermarket fuel lines added including the hand primer which I do not think is standard (I did read online a lot were replaced under warranty). However, the fuel lines mine has are really really long and run around the engine bay from the fuel filter to where they go into the cylinder (I cannot imagine Mazda fitted them like this under warranty). I would put a photo up but I cannot figure out how to.......They are so long I have to manually move them out of the way when I want to close the bonnet :(

Could my problem by connected to the really long fuel lines fitted as I cannot imagine you are meant to hand prime your car everytime you want to start it from cold?
