2009 ls 460 starts after leaving over night also if i crank it within a few minutes but leaving it for more than five min after cutting it off starting takes two cycles it just turns as if it's not getting any gas, but runs fine after starting. Lexus of austin said i needed to replace the high pressure fuel gaskets, both sides and rear pump assembly, completed the repairs same problem, i'm hot!!!! After that also had fuel injectors cleaned, same problem

Who did the repairs? You or them? Honestly the problem does sound like it's fuel related, if they did the repair you obviously can bring it back and they'll have to "fix" the problem and your entire financial commitment to them. However if you did the repair or had an independent do the repair based of their diagnosis? There's nothing you can do.

Hig pressure pump gaskets? Hopefully we're not talking about the gaskets to the valve covers because that wouldn't solve any of your problems. And the fuel pump? I'd think that if the car would/was staying running once it was started, the fuel pump wasn't the culprit. Now perhaps a pressure valve - something that holds fuel line pressure when the car isn't shut off - could be the issue, but I wouldn't assume it's the fuel pump itself unless the thing just had no fuel pressure, or very low fuel pressure while running. I dread the day I have fuel issues with this car, with two fuel systems and three fuel pumps...not something I want to get into...plus the 16 fuel injectors. Good luck. Hope it's something simple. And look on the bright side, replacing the high pressure fuel gaskets are something you'd probably have to do sooner or later anyway. And you can probably sell the fuel pump they took out as well.
