When you turn the key do you hear the pump prime?
Give the bottom of the tank a few good smacks with some wood to see if you can get the pump on. Or remove the access panel in the trunk and try tapping it that way.
If it's done I would try and get a low mile stock one or replace just the pump with another stock or OE replacement.
Changing the pump isn't too difficult but sometimes the lines can be hard to get on and off the canister and pump.
Don't get one from a parts store, too expensive. ZZP/Wbody store should have one for a good price or Rockauto.
No need for a write up, it's quite easy. Remove access panel in trunk, unplug fuel pump harness and fuel lines, remove C-clip holding the pump assembly into the tank. You'll ahve to wiggle it around to get the float out as well so be careful not to break it.
Once the assembly is out it's self explanatory. Disconnect 2 lines, remove socks etc and rremove pump from the assembly. Reassamble in reverse order.
OR you can get a whole assembly. Check CGP classifieds or ask around, someone should have one.
