May be the Crank Position Sensor is not working well. It sends out the RPM signal to the PCM. If it is bad, there is no RPM signal, and the PCM may not command the ignition module to fire the plugs. It could also be the ignition module or pick up coil as well.

I wold expect the fuse box is either under the hood or in the dash. I'd need to see it to locate it for you.

The Crank Position Sensor sends out the RPM signal to the PCM. If it is bad, there is no RPM signal, and the PCM will not command the injectors to fire. You would need to find the output signal wire and check it with a digital storage oscilloscope to see if it is sending out a signal.

I'd need to see the vehicle to tell you where the components are located.

There are probably online sources with instruction guides on the internet. Google "free online repair guides" and you should be able to find some service information.

If you need a step by step procedure, you will have to buy a service manual for the vehicle.

Also check youtube as many people have posted videos of simple repairs

Since you don't really have adequate diagnostic tools, I would suggest just changing the crank position sensor (Most are under $50.) and go from there.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
