Ok, my truck has been hard to start for quite some time. I finally got around to hooking up a fuel pressure gauge and it does not hold pressure. When you first turn the key to on the fuel pressure primes but as soon as you hear the pump turn off it drops from 60/62 psi to around 50 and then slowly creeps down. When I go to start the truck it will jump back up to around 60 psi. With the truck idling it sits anywhere between 50-52 and if you give it some gas it will jump up to about 59/60 psi. When you shut the truck off it will hold pressure until you here the pump shut off and then it drops to 50 and will be at 40psi within about 10 seconds. If you leave and come back in a few minutes it is around 5psi and will eventually go down to 0.

So, my questions is would this be a faulty fpr, injector leaking, or bad fuel pump?

Yup, I'll go with FPR myself. The one on my Ford did the exact same shit.

That's what I figured it was. I went ahead and ordered the entire spider assembly and will be swapping it out when I am off work the last week of April.
