25 not starting issues :(

Evening guys...



The inlaws have got a 2003 25, recently it had developed an issue of not starting when it was warm, it would take up to 10 flicks of the key before it would fire.



So I've replaced -

Spark plugs

Coils

Cam & crank sensor

Temperature sensor



It has now developed the issue of not wanting to start from cold now, so they got it plugged in and the fault codes were link to the following, so I've changed those parts -



Maf sensor

Idle control valve



Non of which have made any deference. At the time of changing these parts I noticed when turning the key, you don't hear the pump prime, so I've checked the fuses & swapped relays which still have made no difference, so I've come to the conclusion that the pump is possibly at fault?



My question is, before I start ******* around dropping the tank out to change the pump, is there any thing else that could cause this non starting issue?
