Hey man. Welcome to the forums. The first thing you have to do is find out what you’re missing when you are having the no start condition. Most likely spark or fuel. I would start by checking fuel pressure (after you have the vehicle to the point where it won’ t start, but just keeps on cranking). Here’s a video.

These are just starting points. Use some diagnosis, and narrow down your problem. Good luck, and keep us posted.
