Fuel pump Doesn't Prime, but runs with oil pressure...

Ok here's my delema, The fuel pump wont prime, but if i crank the engine, soon as oil pressure starts the pump turns on, Or i can hit the diagnostic port and she will start a little easier.

What can i do to make it prime once again?

Anyone have a diagram for the pimeing circuit?

Sounds like a failed fuel pump relay.

where is this relay exactly? Having a hard time finding it.

The car sucks trying to start because i have to work up oil pressure before there is fuel pressure.
