Isuzu 4HL1 diesel, what is the course of trouble? The engine is normally running in good condition then I park the truck, stitch off then after a few hours I start the engine and it will not, until now it is my problem. Why?

This could be a number of things but the most likely is a fuel issue. However, let's start with this guide that will walk us through getting started:

Then we need to check the fuel pressure when this happens to confirm this.

Here is a guide that will help with this:

If the pressure is low we need to check the filter before you replace the pump. So I attached this below for your review.

Let us know what you find with this and we can go from there but if it turns out to be the pump, here is a guide that will help with replacing that as well:
