If you let it sit for more than 15 minutes after you shut it off it won't start again for a few days. I'm stumped. Put in a new computer and still have the same issue. Any pointers before I throw a match in it? 😂

 

5.7????

What's missing when it won't start, spark, or fuel?

 

It has no spark.

 

The engine should be a 5.2 (318) or 5.9 (360). Which one do you have?

 

Damn autocorrect, it's a 5.9. I've tried to change it 3 times but it won't let me.

 

Are you getting spark coming off the coil? Also, is the check engine light on? If so, have you connected a OBD2 scanner to see if there are any pending or stored codes? Try this video to diagnosis further and let us know what you find -
