Where is the starter realay on a Pontiac gto?

The Pontiac GTO's starter relay location varies slightly depending on the year. There isn't a single universally located "starter relay." Instead, the starting circuit often uses the Powertrain Control Module (PCM) to control the starter solenoid directly, or it might use a relay integrated into a larger fuse box or underhood fuse center.

To find it, you'll need to consult your year-specific Pontiac GTO repair manual or online forums dedicated to that specific year model. Search online for "[your GTO year] Pontiac GTO fuse box diagram" or "[your GTO year] Pontiac GTO starter circuit diagram". The diagram will show you the location of the relevant relay or the PCM's role in the starter circuit.

Looking in the underhood fuse box is the most likely place to start your search.
