More fueling issues (I think)

Hi all. I imagine my questions have been addressed before, and if so, feel free to direct me to the original threads, but I'm hoping to get some answers before it gets too cold out.

The truck is cranking, but not starting up. It occassionally gets a little smoke coming out when it's cranking and it acts like it wants to fire up, but it doesn't. I went to relieve the fuel pressure, and when I opened the drain valve behind the fuel bowl, nothing came out. The Chilton's manual says to check the fuel pump fuse, but I can't find it. I also thought about just replacing the fuel pump, but I don't have the special fuel line disconnecting tool the book says I'm supposed to use. My questions are as follows:

Where is the fuel pump fuse on an '02?

Do I need a special tool to disconnect the fuel lines, or can I get away with using a regular tool? if so, what tool do I use?

The batteries are fully charged, so before beginning to tear apart the fuel system, is there something else I should try?

I appreciate any help you folks can provide. I would just take it to a shop, but if I can't get it started, my only choice is to become a shadetree mechanic, but since all the leaves are gone, it's not really a shadetree. That was an attempt at humore, but it probably failed miserably.

Thanks in advance

You can pull out the fuel filter and turn the key on and see if it fills up. Your manual should say what fuse the pump is.
In the batt junc box, #5, 5A mini, fuel pump relay coil.
Batt junc box, #19, 20A maxi, fuel pump motor, PCM.
When it cranks, do you show oil pressure or any tach movement? How about key on, but not cranking: Does the WTS light come on?

Without a filter element in the housing, the spring-loaded platform it sits on blocks the flow of fuel into the bowl (unless it's been eliminated) to prevent people from actually running their truck without a filter.

I would use a test light to check for power at the pump but, remember the PCM only allows the pump to run for 15-20 secs without the motor running for Fire Safety in a crash. Cycle the key to reset.

If there's no power there then the next thing to look at is the Inertia SW in the passenger kick panel. From there it activates a relay built into the fusebox (on an '02)

Look in the Owners Manual for all the fuses, if you don't have one download it here -> https://www.fleet.ford.com/maintenan...ls/default.asp
