Question Why is it hard to Start when Cold

Now this is a strange one .... Let me give you a Update
As you all know I recently had the head off well that's all good runs crisper and cooler...
Before the headjob you had to crank it a bit hot or cold now when its hot Perfect... just first start of the day I am running on fuel at the moment LPG Pump is broken ... closest pump is a Barcaldine 106k away (Joys of the Outback) plugs are new coil dizzy rotor leads all under 10000k sensors are good fuel pressure is my next thought for that I will have to get a gauge off ebay as mechanics don't have one
But fuel pressure would affect it hot or cold ? but when its cold I have to crank it 2 or 3 times might fire on the second and still need a third to start might start on the second every day is different when it warms up first time every time straight to idle and runs smooth any ideas

Have you tried turning key on & wait till pump noise stops 2 or 3 times then see if it starts straight up?

On cold start doing this my XJ will take a few cranks (3 odd) to start. When warm, 1 crank will do it.

the battery is fine I tried this today Cold start 1 pm turned the key on and waited for at least 30 sec maybe 45 sec then cranked First Go! I usually wait for a bit anyway to allow for fuel pressure to build up when its hot I usually only wait for about 10 sec before cranking First Go every Time so I might try waiting for a bit before cranking and see how that goes the fuel pump was replaced about 3 yrs ago and normally is only used to start before the gas computer turns it off might be a bit weak?

When you turn the key to run, (the position befor crank)the fuel pump will run for 3-4 sec then turn off, not much point waiting longer than that. If you listen you can hear the pump run and then shut down.
Good luck with it
