I looked at a schematic and it does have an oil pressure switch and also a relay. It looks like it starts on one power source from the oil pressure switch then the relay connects and also powers it at the same time or maybe the relay powers it at first then it switches to the oil pressure switch, I'm not sure. It also has a wire ran to a terminal on the DLC connector under the dash. You could easily put power to that terminal and it will run the pump then see if it starts easier but it looks like that circuit goes open when the relay gets energized. First schematic is with an ECM and second is with a PCM not sure what you got. They are similar. The PDF is the whole powertrain management in color.

I always thought the oil pressure circuit is just a backup for fuel pump relay. Shouldn’t be the primary setup.

Honestly I like them for standing on to get over the side of the box. They are strong… must be if I can bounce on them! Lol!

One other thing is Colby is going to use it for college and it will be parked on the road we wanted it to look a bit shitty so maybe some crackhead will leave it alone!?
Wish full thinking!
