Instead, the starter motor is engaged by a complex interaction between:
* Ignition Switch: This is the primary control.
* Neutral Safety Switch: Prevents starting unless the transmission is in park or neutral.
* Several Fuses and Circuits: Protecting different components involved in the starting circuit.
* The Starter Solenoid (on the starter motor itself): This is an electrically controlled switch that activates the starter motor. It's the closest thing to a "relay" in this context.
To find the problem with your Seville's starting system, you should check the following:
1. Fuses: Check the fuses related to the ignition system and starter motor in the fuse box (usually under the hood).
2. Neutral Safety Switch: Ensure it's working correctly by checking that the car only starts when in park or neutral.
3. Ignition Switch: This is a complex component and often a point of failure. Testing requires specialized tools or knowledge.
4. Starter Solenoid: This is located on the starter motor itself, usually on the top or side. You can often hear a click from it when the ignition is turned, indicating the solenoid is trying to engage but may be faulty.
5. Battery and Cables: A low battery or corroded cables can also prevent starting.
What the Starter Solenoid Looks like: It's a small, cylindrical device usually attached directly to the starter motor. It has large battery cables connected to it and often has one or more smaller wires going to it for the electrical control.
In short: There's no single "starter enable relay" to locate. Diagnosing a starting problem requires a more systematic approach to check the components mentioned above. A repair manual specific to your 1991 Cadillac Seville will be invaluable for this process.
