2002 won't start
I have an 2002 F-150with a 4.6 liter&approximately 45000 miles, started fine this morning, got off work and just turns over. No noise from fuel pump and checked fuses and relays. Would this likely be the fuel pump or is there something else I can check before dropping the tank.

I parked my 2004 5.4 F150 at the Philadelphia airport on Sunday. Flew back from LA on the redeye last night and the truck wouldn't start.....I could hear the fuel pump prime, I reset the inertia switch, checked the injector fuse (all good). I'm going to let the temp rise a bit and go back and see if it'll start. It's either fuel or spark.....Hmmm.

BUT, this morning was another cold day and the truck will not start. It turns over but does not catch...............I'm getting impatient, I just bought the truck 3 weeks ago and I am already having issues.

I wonder if you have water in your system, since gasoline doesn't really freeze but gets thicker, and shouldn't do any such thing above -200C which is really cold...
Perhaps adding some water-removing/fuel conditioner to the fuel tank would be in order, it might also be worth changing the fuel filter. It could also be that some component in the fuel system (or elsewhere) is just not functioning, which could mimic this behaviour. (of something freezing)
It could also be that if it's that darn cold, the oil might be too thick for it to turn over?

Wow a lot of misinformation here! and some good!
If your fuel line is frozen which is very possible. once it starts again change the fuel filter and use and isopropyl based fuel line dryer. then once that tank is gone fill er up and run some GOOD fuel system cleaner through. (BG 44k, Techron)
Your check engine light is due to the cold start up and when a gas engine first starts it produces a massive amount of water which can soak an o2 sensor and throw a code, especially if they are old. very common make sure you are really warming the truck up. (30 to 40 min drive)
NEVER EVER disconnect the POSITIVE wire first!!!! You can cook all sorts of electrical components including the ECM!
Cheap spark tester WILL NOT properly diagnose ignition on a computer controlled engine! Just because there is spark it doesn't mean there is ENOUGH spark.
good luck-

I changed the filter and it didn't fix the problem. I bought a scanner and I got the following codes.
P1235 Fuel Pump Control Out of Range
P2105 Throttle Actuator Control Forced Engine Shutdown
P2107 Throttle Actuator Control Mod Processor
P0606 PCM Processor Fault
I then put a space heater under the hood and warmed the engine bay for 15 minutes......the truck started right. The temp outside was above 35* so I doubt it is fuel related.
Once I had the truck running I decided to drop it off at Ford to have it checked out.
