Is there a fuse and relay on a GMC Truck?

My friend has a 07.5 chevy with a fuse and relay but in my 09 it doesn’t. My truck kept dying on me and throwing codes. Ended up being the module above the spare tire not being sealed correctly from gm. Definitely was confused tho when I didn’t see a relay or fuse…

Where is the relay on a GMC 6.2?

Those “gem” threads answered it perfectly. Relay is above the spare tire. My 6.2 is strong and sexy, but it still needs help sucking it’s own gass. Lol It’s crazy how GM can make (what seems to me) pretty major mods by adding relays here and deleting fuses there, but forgetting to update the manual and fuse box diagram.

Where is the fuse for the ECU located?

Locate the fuse for the ECU using the fuse diagram on the underside of the fuse panel cover. Pull the fuse for the ECU using the fuse pullers in the fuse panel. Turn the ignition to the “On” position but don’t crank the engine (it won’t start anyway).

Why does my ECM 1 fuse keep blowing?

If the wires leading to the O2 sensor rub against the exhaust, it creates a ground; once the O2 sensor is grounded, the fuse to the ECM 1 blows. The O2 sensor must be installed in a different place to ensure the wires do not short-circuit.

What causes a fuel pump fuse to blow?

When the fuel pump begins to fail it overheats, causing it to drain more amperage (amp); if the amps exceed the amount of amps the ECM 1 fuse allows, the fuse will blow. Replacing the fuel pump should correct this problem. The ECM 1 operates via voltage sent from the battery.
