Weird spark plug problem?

Weird spark plug problem?
The #1 cylender sparkplug on my truck burns the ground really bad on this plug to wear the 90 degree part of the plug is all burnt up. The #1 cylender still fired and fires with this bad plug and it misses also if you run the truck with the injector wire off so im getting spark and getting fuel and a injector pulse fuel pressure is 47lbs anyone think it could be a injector problem where it is not getting enough fuel making the ignition too hot?

Like you say, that does sound strange.
If it were happening on my truck,
I would pull the distributor cap and look at the post for that cylinder too,
and measure the electrical resistance of the ignition wire to that cylinder.
then, if I found nothing unusual I would put a new spark plug in that cylinder,
as defective metal in the ground strap of the old plug could also cause that
pitting and burning of the ground strap.
Dodge has admitted that their orignal arrangement of ignition wires allowed
'cross fire' of one cylinder to another when the wires were too close to one another.
Their 'fix' is a highly unusual arrangement of wires that you can do step by step using these instructions:

The first thing to try fuel injector wise,
is to do the simple, cheap and easy first,
so put a bottle of official Chrysler Fuel Injector cleaner (about $7)
in your gasoline with about half a tank so that you mix with no more than about 16 gallons.
It would not hurt after than 16 gallons with the Mopar FI cleaner,
to buy a $10 bottle of Chevron Techron Concentrate Plus (the "Plus" version is important) and add that to the next 16 gallons.
I would not even argue with doing a third mix of 16 gallons with Yamaha Ring Free ($19)
It is very common for the factory fuel injectors to develop deposits at their tips and 'junk' in the catch screens. Many times it takes three bottles of FI cleaner to clear deposits and reduce carbon deposits.
If that does not clear up the problem
then buy at least 16 new o-rings,
pull the fuel injectors and rail,
inspect everything including the little 'catch screens' at the top of the injectors,
and swap the fuel injectors of cylinders 1 and 2
before putting everything back together using the new o-rings with a bit of lubricant on them to prevent damage during the re-install.
If you find rust particles in the catch screens you need to replace the whole fuel line going back to the pump assembly submerged in the tank.
good luck

i hope in the new 2009 Ram they put a fuel pressure sensor so that the PCM computer can set a trouble code for when the fuel pump is dying
many, many 1994-2004 owners have had to diagnose a dying fuel pump
with no clues from the 'check engine codes'
and it is particularly hard because it will have satisfactory pressure one minute
and drop to near zero the next minute

That almost sounds like the incorrect plug wire on the spark plug or the distributor cap. Retrace all your wires from the distributor to the plugs.
