03JGC 4.7 HO blows injector fuse when flooring it. Before this installed new alternator,starter and rear upper control arm,since ASD relay to no avail,please help.
Bad injectors can cause this also, most have a resistance of about 14 ohms, but can drop much lower with age or contaminated fuel, which causes more current draw (amps). Go to the parts store and see if they have one for your model, then use an ohm meter to see what the resistance is for a new one, then compare that to all your injectors.
Replace any that are 2 or more ohms lower in resistance.
