I have a 06 f250 6.0 crank no start. Injectors are not clattering when ignition is cycled on. I have 58amps at the ficm when cycled. Is that to many volts to keep the injectors from cycling.
Hope you charged diag. Times are tough, but battery replacement is one of the least expensive repairs a 6.0 will ever need. I’d like to buy a newer truck, but factoring in maintenance and repair costs makes it unaffordable.
