I have an 08 F450 that I changed out the oil, oil filter and both fuel filters on yesterday. Tried to start it up after I was done and nothing. I got it to start a few times, but would die after about 3-5 seconds. I have the wrench and oil pressure warnings on the dash display. I've checked the filters, they are installed properly. This is the first SD/ deisel I have owned, so I'm not too sure what the deal is. I got about 5 gal of oil when I drained it. The manual said it should only take 15 quarts to refill. Any suggestions?
Verify that you seated the frame fuel filter fully then cycle the key a few times to purge air out. If that doesn't do it then it is time to trouble shoot the fuel system.

Turn the key to the ACC position... you will hear the fuel pump working for 30 seconds. After 30 seconds, turn it off and then turn it again... let it sit in ACC for 30 more seconds.
Do this 5-6 times. It will cycle the fuel and get the air out of the filters (and entire system) you just installed.
Should crank right up after this.
This method is recommended when you drain the water separator as well.
If just turning the key to on does not allow it start try pushing down on the fuel cutoff switch while cranking.
Some switches are hypersensitive. Switch is located on the passenger side front. Open the door and you will see the access panel on the side of the dash.

Had the same problem with mine and like you it had me a bit concerned because my 2003 6.0 never did this. It took quite a few attempts (10 - 15 minutes or so) but it finally lit off and runs fine now. Like you I would get some partial starts but I could not get it to run at first. Guess the air had to work its way out of the system.
Not sure why the 6.4's do this when the 6.0's did not but that seems t be the case.
You shouldn't get anywhere near 5 gallons. 15 quarts is all you should get. I change my own oil and have never gotten any more than 15 quarts. Aside, that's what your manual tells you to put in (just pointing it out in case someone wants to argue with me).
There's something else wrong. Take it to the dealership ASAP.

I got close to 5 gallons out of mine when I changed the oil. Called the dealership, they said it was because I had extended the oil change interval because I am running synthetic and because of when the truck goes into regen some diesel fuel makes it way into the crankcase. They recommended that I drop back to a 5K oil change interval, kind of defeats the purpose in running synthetic?

No it can happen. Most that are making oil are seeing 1 to 1.5 extra qts just in the 5k mile change interval. Seeing 4 extra qts over 10k miles (two change periods) seems likely. This is a very serious problem with the 6.4 and you just can't go with extended change intervals with this engine. Most change the oil at 5k some change it at 3k because of the oil making issue. I have heard (although not confirmed) that Ford "ok's" up to 11% fuel in the oil. That would be 2 extra quarts...
The dealer claims diesel fuel in the crankcase broght it close to 5 gallons?
You had a gallon of diesel in your cankcase???
B.S. More than likely, you didn't correctly measure what you drained.
All right Hot Shot, I drain my oil into a 5 gallon bucket. When I drained it three weeks ago I came within 2 inches of the top. You tell me what that measures?

I'm pretty sure that when I took the drain plug out of the oil pan... it drained into an open top pan that had a sticker on it that said it had a 5 gal. capacity. It filled to just below the top of the pan. If that's not at least 5 gallons, I'm not sure what is. I'm not a complete idiot.

I say you're not using a calibrated bucket or you put 5 toomany quarts in your engine.
