Hi guys I own a 05 Gallardo when I refuel the car with a hot engine it fails to start. Electrically the car try's to start but it feels as if fuel is not getting through. After turning the key 5-6 times to prime the pump the lambo will start on what feels like 2 cylinders only then slowly comes to life.Refueling when cold is not a hassle any help would be appreciated also has anybody else had this issue??? Cheers Andrew

Thats a wierd one.  Same car but mine starts better hot than cold.

Does it only do it after refuelling?  If so, bad purge valve would be the likely suspect.  If stuck open, fuel pours into the engine flooding it during refueling.  The car should throw a code for that, have someone stick a scanner into it and look.

Sound like it could be a fuel pressure regulator problem if you have to prime the line again.  I guess you need to stick a pressure gauge on the line and look at the reading when you turn the ignition on when hot.

Yep strange, Not a problem if I drive a short distance to refuel the car will start first attempt, but if re fueling a hot engine it will not fire up until I turn on & off about 5-6 times
I had the car serviced last Wednesday 20/1 & no faults had been logged
Thanks for the feed back guys
