electrical problem and no fuel pressure

[camino70]

I went to start my car the other morning and the fuel pump didn't prime when I turned the key, there was 0 pressure. I put power to the test connector and there was fuel pressure. It then started and I needed to get to work. Later, same thing, no fuel pressure. I checked out the relays and they are all gummed up, I am assuming it is insulation in the relay or connector getting hot and oozing out. I cleaned the connections up and got home with the car. I can't find a short anywhere and don't really know what else to look for. Any ideas for me to look into would be greatly appreciated.
TIA

Ron, sounds like the fuel pump relay has died and the car is running off the back up circuit thru the oil pressure sender.

The fp relay is the one on the passenger fender with pink/black, dark green/white, black/white, and a gray wire on it.

When the key is turned on to "run", the pink/black wire is hot.

Looks like the green/white wire should be hot for a couple of seconds when the key first comes on. It should also be hot if I am looking at it correctly, when the engine starts.

Black/white is ground....gray goes to the pump and the test lead.
