Does it continue to start and restart every time you try to start it? If so ,we need to check fuel pressure and make sure it is not bleeding off as soon as the truck starts.

Here is a guide that helps with this:

Also, we need to make sure the air flow rate is correct. I attached the process below that will help with this.

Let's run through this material and we can go from there. Thanks
