    turn your caps lock off,if it started ok but cut out over 40 id suspect other issue than pump and injector washers that usually show poor starting too ie excessive cranking to start

    up until last oct it started on the button, the garage said at the time it was one of 3 things, once they changed the seals after the pump it was ok until recent when it started to not start, when I can get it to start you can hear the pump all the time. The AA used brake cleaner via the air intake to get it going when I broke down last week

    So it's about a starting issue or it stops while driving too ? anyway from these symptoms to jump to cracked head conclusion is quite exagerated... it can be as simple as crank sensor signal failure or other management issue, was it scanned with a dedicated diagnostic tool? if not the discussion is feckless

    yes it is a starting issue and it just stops while driving . Breakdown guy said if i had driven no more than 30 mph the car probably wouldn.t just stop.The garage say its a cracked head but have not suggested anything else, Another breakdown guy said it could be fuel pressure regulator but the garage said no. When the breakdown guy got it started he plugged his device in but no fault codes came up . Thanks for advice

    have they checked fuel pressure,and flow by removing the drain plug on the bottom of the filter then switch ignition on,should flow like a good running tap not splutter,the factparts have been changed at some point doesnt mean they cant be faulty

    Can't a cracked head be diagnosed with a compression test or a leak down test?
    Or is that just too old skool?

    IMO the symptoms described cant be caused by a cracked head just like that. The vehicle must be hooked to a diagnostic tool

    You can try yourself to rule out the air bleed valve(WJN5200110) cos that one used to cause such issues especially when starting but in rare cases it can make it cut out too, it's in the rear outer port of the filter head, easy to replace...if you replace it run a purge before you crank it
