No this vehicle does not have an inertia switch like Ford's do. so we need to start with this guide that will get us started:

Basically, you need fuel, spark, and compression to start the engine so we need to find which one we do not have in order to figure this out.

Let's check the fuel pressure and that will show if the pump is coming on. That will prove out the relay, ECM control and wiring as well as the pump, if you have pressure.

Then pull a plug and hold it against the block and crank the engine to see if you have spark.

Let's start with this and go from there. Below are wiring diagrams if we have no fuel pressure to check for power.
