That fuse supplies power to a number of different components including the fuel injector, ignition coil, ECM, ignition coil, crankshaft position sensor and vehicle control module. A faulty component, or short anywhere in this circuit, could cause driveability problems and blow the fuse. A professional, such as one from YourMechanic, can pinpoint the stuttering issue and get your truck running right.
