Troubleshooting a no start problem on your Ford 4.9L, 5.0L, or 5.8L pick up, van, or SUV can be easily done, with the right diagnostic information and troubleshooting strategy... and in this article I'll provide you with some of both.
In this article, I'll shed some light on the most common problem areas and more importantly, where to find the info you need to get to the bottom of the problem.
Here are the contents of this article at a quick glance:

Since a lot of folks confuse a no crank condition with a no start condition... I'll clear it up right now:
In a no start condition (also known as a cranks but does not start)... your vehicle's starter motor is cranking the engine but the engine is not starting. This is usually due to a lack of spark, or fuel, or engine compression and in this article I'm gonna' explain in some detail how to diagnose this type of condition/problem.
In a no crank condition, the engine is not cranking when you turn the key to crank the engine. In other words, you turn the key and nothing happens... since the engine won't turn over. This usually due to a BAD starter motor or a BAD starter motor solenoid.
Remember... this article only deals with a no start condition.
What's gonna' help you to 'hit the nail in the head' (when diagnosing a no start problem) is that the issue will be in one of three distinct areas. It's either gonna' be in the ignition system, or the fuel system, or in the engine (mechanical).
Remember, the engine needs air, fuel and spark to start and when it's not starting... it's because one of these three components is missing from the mix.
Let's take a brief look at each area (system):

OK, now that you now what are some of the components involved in getting your Ford pick up (van, SUV) to start or not start... let's take a closer look at some testing info in the next subheading.
“For instance, on the planet Earth, man had always assumed that he was more
intelligent than dolphins because he had achieved so much —the wheel,
New York, wars and so on —whilst all the dolphins had ever done was
muck about in the water having a good time. But conversely,
the dolphins had always believed that they were far more
intelligent than man —for precisely the same reasons!”
