I just purchased a 1998 F-150. I've been driving it around...nothing
special...for two days now. I was filling it up with some gas, and
tried starting it...

It cranked over fine...the new battery had plenty of juice...
But it wouldn't "catch". It just wouldn't start...I let it sit five
minutes...tried it again and it fired right up...

Apparently the main computer on the truck was just replaced at the
dealership too.

SHould I be concerned...? Maybe just old fuel ?? Maybe a fluke ?

Do you recall smelling varnish at the gas station? You couldnt miss it
if it was old gas.The fumes would be pushed out while you were
pumping.
Also i doubt its old gas, since you drove it for 2 days, and the icing
on the cake is the ecm being replaced. Tells me it may have been
happening for a while.
Also your discription of "nothing special" doesn't not give the vital
info needed, like what is powering the truck .. 5.0L? 5.8L? Mouse on a
wheel?

Does it look like the idle air control valve was replaced recently?

LoL...mouse on a wheel...

Well I meant old fuel in the car's tank, finally getting into the fuel
injection.

IT's being powered by the 5.8 L V8. If it helps, I had been starting
and stopping the truck alot before filling up (Xmas
shopping...ugh)...maybe a hot engine ?

Im worried it has something to do with the ECM. (forgive my lack of
skill / knowledge here), but If it's not a fuel delivery / quality
problem it has to do with firing times, governed by distributor via ECM
(?????????)

The 5.8L V8 was not available in 1998.

A 1998 F-150 would not have a distributor.

Hard starting after re-fueling is symptomatic of a leaking purge
solenoid.
The purge solenoid would normally only be open during cruise
conditions, purging the evaporative system of fuel vapors.
When the purge solenoid sticks open while re-fueling, gasoline
vapors flood the intake manifold creating a flooded engine
condition. Your 5 minute sit was enough to let the vapors
dissipate.
