Inertia switches are a troublesome Ford thing. What is the exact symptom? Does the starter crank the engine? Is everything out, including the instrument cluster? What is the correct engine size?
The first thing you need to do is read and record the diagnostic fault codes. Chrysler made doing that yourself much easier than any other manufacturer. Cycle the ignition switch from "off" to "run" three times within five seconds without cranking the engine, leave it in "run", then watch the code numbers show up in the odometer display. List any codes in your reply and I will interpret them for you, or you can go here for the definitions:
You need to check for spark in the normal fashion, and check for fuel pressure. Try to listen for the hum of the fuel pump for one second after turning on the ignition switch. If you have no spark, start by inspecting the connector and wiring for the crankshaft position sensor. It is important to understand that sensor's circuit can have a problem and may not set a fault code just from cranking the engine, so we cannot assume it is okay if there is no code related to it.
