**911** Help!
Ok guys here is what is going on. Went to leave this morning and the truck cranked over but wouldn't start. When I let off from trying to start it, the starter continued to turn over for a few extra seconds. It has done this before, so I cycled the gears when it did it the first time and it started. Well this time, it started but felt like it was missing. First thing that popped in my head was plugs. So I went to get some plugs (in the mustang 
) came back and put them in the truck. Made sure everything was good. Checked the owners manual for gapping and they said .040 to .050 so I split the difference, anti seized the threads, torqued them down to 24ft lbs., made sure everything was connected and back in the proper spot and went to start and it wouldn't fire at all. All the fuses were good and have spark. I am at a loss. Any ideas? I need this fixed quick, since its my DD. Thanks.
Edit: I was going to check the fuel pressure but didn't see a valve. Also, the check engine light flashes. Maybe I can get a code reader from somewhere.

Are the plugs coated with fuel or dry? I'd say the safety fuel inertia switch is tripped if you aren't getting fuel. Also, when was the last time you changed your fuel filter? After the truck sits for a while, the crap that is in the filter settles and can gum it up so that you aren't getting enough fuel.
When you say it doesn't fire at all now that you have replaced the plugs, does it not even crank? Or just zero signs of life but cranking?
PS, the starter will continue to crank over unless you turn the key all the way to off. Some of these trucks have that function, while others do not.

The old plugs are dry. Where is this switch at? I have no clue on these things, I know my mustangs is in the trunk. And it wasn't sitting but over night but I just changed the fuel filter a couple months ago. And that's good to know about the starter, that had me a little worried. Ill google where the switch was.

also check the condition of your fuel pump driver module located under your spare tire ... it get's corroded and splits open where it mounts to the frame rail.

Here was the issue:
Ended up having a broken coil rear coil on the passenger side at the base of the connector, so I replaced that, and the intertia switch was popped. Not sure why or how it would have by just sitting over night, but it was. But on a side note, I took off the fuel pressure regulator to get to the front coil and plug a little easier. Well while reinstalling it, the small o-ring must have been bad, or going bad and when I removed the sensor I just finished off the job a little more quickly. So when I reinstalled it, it started shooting fuel out of the engine bay. Ford could not pull the part up in their system or the FPS (makes sense for Ford). So I went to Home Depot and matched up the o-ring (had to buy a whole pack of 16for 1!). Put everything back together and it fired right up. The truck does run a lot smoother and idles so much better. And BTW, that intertia switch is hidden behind the fuse panel for future referance to anyone else who runs into the same problem.
Now its time to wait for the 2015s to come out and get rid of this one!
I will check that just for the simple sake for a piece of mind.
