Yes there is a fuel pump relay. I think it's under the dash. There's also an oil pressure switch on the back of the engine next to the distributor. That thing will switch 12V to the fuel pump if there's adequate oil pressure.
The pump should run for a couple of secs w/ koeo and repeat if you shut it off for 30 secs. It should start running immediately when cranking.
You can can check the pump by putting 12V on terminal G of the ALDL, it bypasses the relay and should run the pump. This is still fused so if there is a prob w/ the fuse or a wire further downstream the pump will not run...or the pump is dead.
Easiest way to check the switch and that side of the wiring is to take out the rubber connector on the back of the engine and jumper the 2 wires for the FP, the 3rd is for the press gauge. Orange should have 12V ign switched , jumper this to the FP wire tan with white stripe. The pump should start running immediately. If not the pump is dead. If it DOES start you have a bad relay and possibly a bad switch. they are wired in parallel so when running the switch takes some of the load off the relay. The engine should stay running even when the relay dies because there's oil pressure. The switch is easily removed, hook a compressed air source to the thing with a rubber hose and hose clamp and carefully blow some compressed air in it, the switch will trip quickly and the pump should start running (with connector connected to the switch of course)
to remove pump, remove gas filler lid and gas bib, poke around in confined area to undo hoses and remove bolts and wiggle, twist and turn the sending unit out
