Gargravarr,There are a few kilo-ohms of resistance on the pump terminals in the tank, though I know that's not indicative that the motor works.
I don't have a lot of experience with Mk2 or Mk3 fuel pumps, but from what I've read, the pump resistance should be between 0.1 and 3.0 ohms.
If the resistance across the terminals at the tank are in the kilo-ohms range, I strongly suspect your fuel pump is shot.
If you have other fuel pumps I would measure the resistance on them to compare. If they are under 3 ohms, then I'm pretty comfortable predicting a bad pump.
Dropping a gas tank scares me so I would double check for comparison's sake.
If you are running 14V to the pump and assuming no in-series resistor, the current should be 4.66 Amps which seems reasonable for a fuel pump.
If you are running 14V to the pump and the pump internal resistance is 2 kilo-ohms, the pump will only draw 3 milli-amps.
I'm pretty sure 3 mA isn't going to give much pump pressure.
Again, I would compare what the other fuel pumps measure.
Good luck getting it going
