Typical fuel filler door problems

I had some time this beautiful weekend and decided to tackle some issues with my 348. Needless to say I ended up with my arm stuck all the way down the fender/C-pillar and with my whole body stretched in all sorts of awkward positions for my neighbors to enjoy.
Progress was swift! I quickly pulled the quite unique magnetic fuel door lock from the cable. With this done I was able to pull the wiring further out and give it a better inspection. At this point I should explain that I have not been using the emergency release to open the door; The whole unit was completely seized in the open position! I am not sure if I'm alone here but the unit looked like hell.
So I take a look at the wiring and it turns out I had a mini electrical fire at the poorly designed connection a few inches from the fuel door. The housing was melted but the connections were fine, I proceed to pry open the plug. After freeing the unit, I douse it in electrical cleaner; still stuck... So I unleash my slightly stupid side and hammer it open! Rinse and repeat a few times and what do you know it now can move, sorta. The next step was to twist the lock pin around and around, then a hefty load of lock graphite and dielectric grease. In the end it worked like new!! I shined it up with some sanding it really was like new.
So I took my refreshed unit and some wiring over to the battery to see if it functions after a few repeated tests, I was very pleased!
I cleaned the connections throughly and placed it back in the housing.
Then I spent the next HOUR or so lining up the fuel door, those of you who have done this I am sure know what I mean!
After all of that I got in the car and nothing, nothing at all happened when I pressed the fuel release button.
So my question is what is next is there a trouble spot I should look for in the wiring? Should I jump off a cliff? Could still be that stupid connection aft the lock, should I just replace that--It really did not look too bad I was sure it would pass current (if there was any)
Well at a loss and confused I need your expertise.

 

Where are all the experts?
Doesn't anyone have experience with this problem, I made time to work on the 348 tomorrow and need any suggestions.

 

Thanks for the replies:
RebelBanker: Good idea. I did check it but will go back and give it a cleaning and some dielectric grease!

Miltonian: I was not aware! I will go give it a look right away, you are probably right as the other connections seemed alright.

Fxdwgs: It is an electro magnetic system, that reverses the charge to open/close. Take your unit out and clean it as I described , it is just sticking in the open (collapsed) position. The magnetic force which pulls it back out (locked position), is not as strong (very weak) as the one which opens it; therefore any dust, dirt, etc will cause it to stick.

 

PS: RebelBanker, your interior is super clean! I think we might have a serious 348 online car show contender here.

 

Noted, but out of curiosity why not? From my experience it enhances connections and prevents rust, or at least thats what I have thought....

 

Miltonian, as usual you were right on the money!
It was the fuse I am proud to say I got it to function.
Thanks for all the advice!
