I still have to get my 2000 working but similar issues, I know for a fact the pump is just gummed up, been through it once now but must have broken something else loose...
Reseal kits are only like $15 for these pumps, not super hard to deal with. I took the starter off and just dealt with the business end of the pump in the back (after taking the top off of course).
There's a check valve and screen in the fuel inlet to the vane pump which could be suspect on yours.
Refurbished pumps aren't super expensive, but yeah, I don't want to do that yet either...
