I have changed the starter, battery, alternator, and spark plugs. Before I changed the starter and spark plugs it was reading to charge system when I ran it longer than usual. After changing the starter, it ran for two days. Now, it's right back to cranking but not starting. When I let go of the key, it still trying to start itself.

We need to find out if there is no fuel or spark. We can assume for now that there is compression so we need to focus on fuel and spark. Try using starter fluid in the intake and see if it starts. Then pull a spark plug and hold it against the block to find out if there is spark.

Here is a guide that will help:

Lastly we need to check for codes.

Let's start with this and go from there. Thanks
