My truck has been having a hard time starting lately. In the morning, I have to crank it for about 15 sec three times before it will start. After it has ran and I stop it, it starts right up (Like at a drive-through window), when I turn the key and "wait to start" my fuel pressure does not build until I bump the starter.

any ideas?

 

If you have fuel pressure after it starts, the next thing I would do is check for an air/fuel leak in the line somewhere. It could be bleeding off after it sits for awhile.
