Cranks but won’t start F-450

Cranks but won’t start F-450 If fuse #30 in the engine compartment fuse box blows repeatedly and it Cranks but won’t start, along with no “Wait to start light,” and no Check Engine light, start your diagnosis by unhooking the fuel heater connector containing the red/light green wire on the rear of the fuel filter water separator assembly. If that solves the blown fuse problem, replace the fuel heater. © 2007 Rick Muscoplat
