Where is the fuel pump reset switch located on a 1999 Cadillac Deville?

There isn't a fuel pump reset switch on a 1999 Cadillac Deville (or most modern cars, for that matter). Fuel pump issues are usually addressed by diagnosing and repairing the problem, not by a simple reset. If you're experiencing fuel delivery problems, the cause could be several things, including:

* Faulty fuel pump: This is the most common culprit.

* Fuel pump relay: A bad relay prevents power from reaching the pump.

* Clogged fuel filter: Restricts fuel flow.

* Low fuel pressure: Could be due to several components failing.

* Bad fuel pump control module: Controls the pump's operation.

* Wiring issues: A short or broken wire can interrupt power.

If your 1999 Cadillac Deville isn't starting or running properly, you should have a mechanic diagnose the problem. Trying to "reset" something that doesn't exist will waste your time and may even cause further damage.
