Ford Capri 1991 Starting issue

[kiwimagic]

Hi All
My 1991 Ford Capri Verde has a issue when starting.
First Start each day starts great no problem.
But after sitting for a few hours it needs to be cranked over for what seems like ages. But probably between 5 sec and 10 sec.
Once started runs perfectly.
I have recently swapped over the fuel pressure regulator from my other Capri the would start first time every time so fuel pressure regulator is good. But still have the second start issue when I fitted it to the Verde..
I all so tried hooking up a relay that is triggered buy the starter which then jumped the test plug which then bypassed the fuel pump relay. But still the same thing.
any ideas why this happens and what is causing this?
