428f fuel pump

Does anyone have a link for the electrical schematic for a cat 428f LBH serial? The fuel primer pump and solenoid aren't getting power. Might be a relay, fuses are good but still no power. Any hints would be appreciated.

    Thanks for the pm, turns out fuse 7 15amp is responsible for supplying power for the heater relay, fuel solenoid, fuel lift pump and the shutoff solenoid and lord knows how many more things! A little corrosion tuned out to be a big problem.
