Okay, driving it acted like it lost five cylinders and shut off. I got it home figured it was getting fuel so I replaced the fuel pump I hooked it up after replacing it primed I guess that's what it did turn the key over no fuel getting to the rail I figured it primed so it's getting power. I've tried jumping the relay but I'm not sure if I'm doing the right relay not marked and there's like 4 right together I don't know color of the wires to figure it out. Every time I think I'm looking at the wiring diagram it's not for my car. So, I have no clue right or wrong. I'm really confused because I've been without a car for two months. Help please if you have ideas, please treat me like a kindergartener I would like pictures of the wires I can make since of if that's what you want me to do. I'm an older type of shade tree mechanic. It needs a carburetor, distributor and fuel pump in the side of motor. I could do that. Thanks for any assistance I feel really stupid on this one. No, my fuse is good. Only one it says for fuel no fuse box under the hood thanks again.

So, there is an oil pressure sender that interrupts the fuel pump power circuit which fail, here are the fuel pump and engine wiring diagrams so you can see how the system works and a guide to test for power so you can see where you are losing it.

Check out the images (below). Please let us know how it goes.
