Trouble starting in the warm weather

I am having trouble starting the disco in warm weather, I've noticed when its been sitting in the sun for a few hours its worse ,it will start eventually after I let it turn over quite a few times , then turn it off then it fires up first time.

Any ideas

cheers

Thanks for your reply Geoff, how would I check fuel pressure, is this something I can do or does it need a pro like yourself to do it Wink

to the left centre of the engine at the rear is a Schrader valve with a grey cap on it,undo cap and cycle ignition whilst depressing valve a little.you should see a good squirt of fuel coming out at about 10psi.Have a good few rags around area as to catch the fuel.a lid of a bic pen or something similar will be enough to depress the valve or something as small as you don't have a lot of room for anything longer.you get about 30 secs from turning the key and to depress the valve on your own.
a fuel filter will be the first thing to try changing and if the is not a lot of fuel pressure its a drop tank scenario and a pump replacement which can be chaged for £30 or so diy or a grand at landrover.
