If you suspect a fuel pump problem, don't try to find an inertia switch – it's not there. Instead, you should:
* Check the fuel pump relay: This is a more common point of failure that can mimic a fuel pump problem. Locate the relay (usually in the fuse box under the hood – your owner's manual will show the location) and try swapping it with another relay of the same amperage rating (to rule out a faulty relay).
* Check the fuses: Again, consult your owner's manual to identify the fuel pump fuse and check its condition.
* Have the vehicle diagnosed: A professional mechanic can use a scan tool to diagnose the problem. This will pinpoint whether it's the fuel pump itself, a wiring issue, the fuel pump control module, or another component in the fuel delivery system. This is the most reliable method for identifying and resolving the issue. Simply assuming it's a tripped "inertia switch" when one doesn't exist will lead to wasted time and effort.
In short, there's no inertia switch to reset on a Jeep Liberty. Focus on diagnosing the underlying cause of your fuel delivery problem instead.
