Cold restart problem

[AkiBruce]

Hello
I have a 2003 9-5 2.3t. The car starts fine and runs well. However if you shut the engine off before it is up to tempreture it will not restart. It will turn over but will not fire. If you leave it to return to being cold it starts as if nothing is wrong. Any ideas ? I have cleaned the throttle body, MAF and MAP sensors and can hear the fuel pump coming on when you turn on the ignition.

EDIT: And of course spark plugs to be in good working order - and correct type.
