the 40 amp fuse is to the pull in circuit on the fuel solenoid it means the solenoid hi amp circuit it pulling to many amps and most likely the solenoid is not pulling in

the solenoid is on the back of the injection pump with a three wire harness connected to a connector by the starter disconnect and put a new fuse and see if it still blows

if not you are going to need a new solenoid

do you know if this has a Tier II engine injection pump with injector lines coming out of the back or with the lines coming off the top of the pump

the information I gave you is for a SR2 system if you have an UPVI monitor then you could also have a bad hi speed solenoid disconnect the outer wire on the solenoid to test that circuit
