If you are not using the distributor / ignition that was in the truck, the fuel relay will not stay applied.
The circuit going through the oil sender will supply power to the fuel pump once there is oil pressure, as others have stated.
The ECM is going to be setting multiple trouble codes so the check engine light will come on.

Ok, not good news. This is what I was afraid of from the start. Question, once we hook up a factory oil switch will the pump run with oil pressure and the ECM
just make engine light come on? Or will the lack of dist signal kill the pump?
We're not using original ignition. Wondering what our best options are. Replacing pump with new electric and delete existing pump. Or installing the original distributor? Or something else?
