starting problem when hot HELP - Saxperience

on my 1.6 xsi (okay, not a saxo, but i'm having no luck with this on the 106 forums, lol) in the mornings, and after leaving it at work for 9 hours a day, it will start straight up. and will do if i start it within 5 minutes of driving it.

yet if left for longer, it will just crank over for at least 5 seconds before it coughs into life.

it started just after i replaced the injectors, even though i had done 200miles between replacing them and the fault happening, and i thought maybe it was fuel evapouration from a dodgy seal, but if that was the case surely it would happen when ever it was started and left for while. also, i have had the injectors off since and replaced the seals just to make sure.

i have also replaced the coolant temp sens, and the crank position sensor.

any ideas anyone? could it be the ecu/relay under the ecu, or another sensor somewhere gone down?

fuel pump?

Maybe fuel isnt getting into the engine very easy?

dont think so, as its fine when cold, surely if it was a weak pump, i would notice it at hi revs? also, if i turn the ignition on and leave it for a bit, turn off and do again to build up fuel pressure it will still just crank over
