NO Power To FUEL PUMP.

I was driving along yesterday and the car started to sputter out and died....After 5 minutes it started back up and ran fine. Then pulling up to a stoplight it died again and would never start again so it was time to call the FLatbed....
Anyways, after inspecting it when i got home...the float boals on my carb are not filling up and no noise of a priming fuel pump....I've had this problem once before and it was the oil pressure switch, replaced it and it worked but I wouldn't think it would be that again....So i pulled the fuel pump harness near the tank and it is not getting power....I then replaced the fuel pump relay but no change.....What do I do next.
BTW...Inline fuse is also good...how do i check the oil pressure switch?
Thanks,
25thredrs

i had a similar problem when i switched to carb

I had to plug in the hei from the distributor to get fuel pump power.

when you pull the relay do you have the power in from the cpu?
If you don't i would check the connection at the dist

I'm not running HEI, I'm running an MSD pro billet distributor with a blaster II coil.
