I am near the end of the process of draining my tanks and plan to replace one pump tonight, if this fixes it I will replace the other or always start my truck on the new pump. I plan on pulling the bed off my truck and doing the pump from the top, is that a good idea?

I think that it has to be the fuel pump. I do not believe that it could be anything electrical or something like an IAC valve. The symptoms clearly show that it is not getting fuel to the motor properly before starting. It's a mechanical issue. It has to be the pump. After replacing the filter and the FPR there is not much left. And the fact that, for me, it started almost immediately after filling the tank and adding fuel system cleaner leads me to believe that something marginal in the system got made a little bit worse`and I think that it will be the fuel pump in my case. I'm not dropping the tank, I'm gonna pay the shop to do it. I will drive it until it's almost out of gas though, to make it easier for them to drop the tank. The less time it takes, the less of a labor charge. The last time that I asked about it it was around $200 plus the pump, I'm ok with that. I'll have a new fuel guage sender put in at the time too.

Most of the time when an engine runs and starts great all day but is hard to start in the morning the engine is flooded from setting all night with a leaky injector(s).
Try holding the pedal to the floor before you try and start it in the morning and if starts right up then you will know if it was flooded or not.
With the pedal on the floor the PCM assumes a flooded engine and will not inject any fuel until the engine starts.
I have also heard of the ECT (the one with the two wires on it) sensor being bad and making it hard to start when cold.
Good Luck

Again - have you pulled your codes?
It is most likely not the computer.
You can tell if it's a leaky injector by doing a leak down test. If you don't know what that is, try a search for it. If you can't find it, someone will chime in and tell you.

subford,
You rock, I changed out my ECT and it started up this morning, still not completely sold my problem is gone, but I did not have the hesitation on initial start up. Definately making progress.
Thank You
Britt

If you have two then you have three fuel pumps, two low pressure and one high pressure.
The low pressure pumps are inside the tanks and the high pressure pump in located on the drivers frame rail.
