i am trying to track a loss of voltage and im not sure how to get any farther than i have. i have 12v coming out of the fuse panel, goes to a connector at the firewall still have 12v goes the fuel pump relay still have 12v but im not sure where it goes after that. coming from the other way at the fuel pump connector i have 8.5v and tracking that all the way thru the car it goes to the dash where i have 8.5v. Can anyone fill in the gap for me?

Did you try jumping the 2 pins on the oil pressure switch, turn the key on and see if you have 12 volts at the pump. If you do not have 12 volts at the pump you will need to replace the fuel pump relay.

Just my 2 cents
