Okay, I know this will sound like a rookie question but bare with me. I cannot for the life of me find the location of my starter relay on this thing. Truck will not crank with the key, but will start up when I jump the starter solenoid. Dug into ecat and found my starter relay should be in the middle of the firewall, but it is not there. Looked in the fuse box by the clutch pedal in the cab, and there is nothing related to starter. No fuse box near firewall. Checked behind the dash, glove compartment, and battery box for any fuses/relays relating to the starter. Is this some weird thing where the starter is controlled by the ecm? There is 12v directly out of the ignition switch when I crank the key, but nothing at the starter.
