"...How to Troubleshoot a No Start in Ford 4.9L, 5.0L, 5.8L
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..."
