While a remote solenoid *can* help with a hot start problem by improving the power delivered to the starter, it doesn't address the underlying cause. If replacing the solenoid didn't solve the hot start issue, the problem is likely elsewhere. Possible causes for a hot start problem include:
* Weak battery: A hot battery struggles to deliver the current needed to crank the engine. Test the battery's voltage both when cold and after running the engine.
* Dirty or corroded battery terminals: Clean and tighten the battery cables and terminals.
* Bad starter: Even with a remote solenoid, a failing starter may struggle when hot. A bad starter motor, bendix gear, or solenoid in the starter itself could all be the culprits. You need a *1967 GTO* starter, not a 1964 Corvette starter.
* Ignition switch: A failing ignition switch may not provide enough power to the starter when hot.
* Wiring issues: Look for loose, corroded, or damaged wiring between the battery, starter, and ignition switch.
* High engine compression: A very healthy engine with high compression can be harder to crank when hot.
* Vapor lock: This is less likely in a muscle car but possible if fuel lines aren't properly routed or insulated.
In short: You need to find a replacement starter *specifically for a 1967 Pontiac GTO*. Don't use the Corvette starter. Focus on properly diagnosing the underlying cause of the hot start problem rather than just throwing parts at it. If you're not comfortable with automotive electrical work, take it to a mechanic specializing in classic cars.
