93 b2600i wont start just clicks

whenever i try to start it all i get is a clicking sound from the round thing on the inside of the fender any help on how and what to fix would be greatly appreciated

replaced the battery and cleaned the connections on the starter relay and now it will turn over but its been sitting for a while and i do not think it is getting any fuel. is there an easy way to check if the fuel pump is working without dropping the tank.

Is there an easy way to check if the fuel pump is working without dropping the tank.

Get under fuel tank and listen. Yell to helper to turn ignition key to "on" position where all the dashboard lights come on, not to the "start" position". Listen again. You should be able to hear your electric fuel pump if it's working. Also, to replace the fuel pump in the tank and/or the fuel tank sender, you don't really need to drop the tank, you can lift and tilt the bed:
Tilting truck bed: Fuel sender, fuel sending unit:

Disconnect cable release and the two rubber hoses at the gas fill assembly (loosen and raise bed slightly [see below] to remove the larger one).
Remove the three 17mm-head bolts on the passenger side bed frame.
Loosen the corresponding bolts on the driver's side, about about 2/3 of the way. Use a 16 inch 2 x 4 on a floor jack to lift up the passenger side of the bed Tighten the jack, and up tilts the bed. I used a 1/4 inch drive ratchet, with 1/4 inch socket and a #2 Phillips bit (and two hands to hold it straight). All mine loosened, but maybe because I'm in Arizona there was no rust; I replaced with 7mm head hex head screws (4mm thread x 8mm long, with a wavy washer). To line up the bed so I could get the three 17mm head bolts back in on the passenger side, the bed needed to be jacked up a little, then I could use my weight to shift the bed a little from one side to the other.
