What does you sitting overnight and your trucks crank have to do with anything?

It has a long crank time when it sits for 30 mins or an hour.

Check the fuel pressure.

I have never in my entire life put 5 fuel pumps in any vehicle I have ever owned. Shoot, in 30 years of being a tech, I don’t think I have put 5 fuel pumps in vehicle.

your grammar skillz make it extremely hard to read what you wrote, but I’d put money on you have a bigger issue. 5 fuel pumps? And they all do the same thing? That is not possible. Take your truck to a shop and let them fix it correctly..or Mr. Turner, you might end up with Will down at Davey Jones’ locker..
