Is my fuel pump shot?

Is my fuel pump shot?
In a nutshell when starting my truck it takes about 3-4 seconds to turn over. I haven't had a chance to hook it up to a fuel pressure gauge yet but my friend who is a mechanic originally thought it was the fuel filter so we put in a new one, and the problem still exists. This probably isn't the best way around the problem but if I turn the key from "OFF" to "ON" (not turning it all the way) really quick twice, then go from "OFF" to turn it all the way over it starts right up. Does this sound like the fuel filter is on its way out to any of you guys/gals? If so, can anyone recommend a good resource of where I can pick a new one up at. By the way, I have 69k miles on it.
Please check my signature for the specs of my truck.

You could just have a bad check valve in the tank. most of them are white plastic in-line valves that just keep the fuel pressure from bleeding off after you shut the vehicle down. It will not hurt anything(if thats whats wrong) to leave it alone, it just gets kinda aggravating. I had to take mine completely out of the system, all i do when i crank mine now is, turn key on, wait 3-4 seconds and then start. It seems to work pretty well.

**Update**
This past Sunday my friend brought home a fuel pressure gauge and we hooked it up. When I cranked it over it sputtered between 10-15 PSI before finally ramping up to around 65 PSI and starting. Once I turned it off, it quickly began to loose pressure diving down to around 10 PSI in a few seconds. When turning the key to the "ON" position it ramped up to 65 PSI again but slowly declined as I left it in the ON position. Is that normal?
