* The starter solenoid: This is the most common solenoid people ask about. It's located on the starter motor itself, typically bolted to the engine block near the bell housing (where the transmission connects to the engine).
* The fuel pump relay (or inertia switch): While not strictly a solenoid, it controls the fuel pump. The inertia switch is often under the passenger side dash, and the relay is usually in a fuse box (under the hood or inside the cab, depending on the model year).
* Shift solenoids (automatic transmission): If you have an automatic transmission, several solenoids control shifting within the transmission itself. These are internal and not easily accessible without transmission removal.
* Other solenoids: There might be other solenoids related to emissions or other systems.
Tell me which solenoid you need to locate, and I'll do my best to give you more precise directions. A picture of the solenoid, or even a description of what it's connected to, would also be extremely helpful.
