09 fat bob won't fire up after being say idle for some time. Cranks over fine, plugs clean and dry all fuses good. No fuel pump sound when ignition turned on so could it be a relay problem. How to test it?
Squirt fuel in carb or tb throat. If it fires fuel problem. You can bypass the relay for fuel pump or check the output terminals if relay for power. I would bypass relay first. If it starts you either have a bad relay or missing signal to relay. Check for voltage to relay and signal voltage to relay. If both present then replace the relay.
It's fuel injected so no carbs, though may check for power at fuel pump itself. Thanks for your help.
No power at FP just confirms no fuel. Depending on how ez to get to FP relay, I'd start with the relay voltage check, both power TO the relay and power out as well as input signal to the relay, i.e., main power relay or on switch on handlebar. You might want to check your bike's wiring diagram and see when the FP gets turned on, i.e., as soon as ignition or with starter.

as long as your volt meter is capable of measuring OHMS you can test wires, find the main power wire to the fuel pump and measure for voltage when you turn the key on(3-4 sec) if power is present at the fuel pump, and the pump don't run, then replace it
SOURCE: It will not start. it turns over and cranks but
even though you replaced it, fuel pump sounds bad....when you turn key on (not a crank)....do you hear a whirring noise from the fuel pump?

possible just not probable. you need to see if there is any pressure to fuel rail. if not youre going to have to by pass the fuel pump and see if it is getting voltage. if so then apply a seperate voltage and ground wire to the pump to see if it kicks on. come to think of it, it could be the PATS system(security) that shuts down the system. it will crank but will not fire. your ford dealer will need to reprogram the system.
