Car stalled on the wife the other day and thought it would be the fuel pump, but it wasn't. No voltage to pump. The fuse was fine and is getting the proper voltage. So, I traced the wiring from the fuel pump relay to the oil pressure sensor (orange wire) and traced the wiring from the oil pressure sensor to fuel pump (gray wire) & everything checks ok no breaks or bad connections. Checked the orange wire (12volt) out of the relay and no voltage, replaced relay with known good one and still no voltage. I Pulled the relay box and checked the connections under the relay all ok. Is there something I'm overlooking? When you turn on the ignition, the relay acts as it should. Clicks on for a couple seconds and then closes as it should. Where would the relay get the 12 volts for the orange wire from? I thought it would come directly from the fuse to the relay to the pressure switch to the fuel pump. Can I run a jumper to the Orange wire coming out of the relay going to the oil pressure switch to see if I can get power to the fuel pump without hurting anything?
Any help would be appreciated as I don't have much hair left anymore lol. Thanks
