wiring up fuel shut-off solenoid

[GRU]

ive got the p-pump on 96 12v that im putting in a 92 f350. what exactly are the red, black, and white wire on the solenoid?

there are actually a few fuel shutdown solenoids, are you talking about the shut off solenoid near the rear of the p pump?

yes it has 3 wires in the connector. red white and black if memory serves.

It's a double solenoid coil. One coil is not enough to pull it up to actually turn the fuel on so for an instant both coils are energized then one will drop off while one coil stays on. I don't have an wiring schematic handy as I'm at work and sold my Cummins long ago but a haynes manual will show you and some of the bigger libraries have them available for check out or just go autozone and open one up and look at the wiring diagrams. but I would bet that the red is hot the entire time the engine is running and the white is only hot during the cranking stage of the game and the black is ground. but don't quote me on that but that is what I would ASSUME.... and we all know what ASSUME means...

I found this while doing a search for it on google...
