Why does my truck not start when I turn it off?

Why do you need to adjust the timing on your car?
How to Adjust Timing. The car’s timing refers to the ignition and the process by which the spark plugs fire, creating a spark in the car’s combustion chamber. Your timing must be at the correct setting for your car to perform at top level, affecting the speed and efficiency at which the engine fires.
What’s the best way to advance the timing of an engine?
Set the distributor to fire at the top (this is considered 0 degrees advance/retarded). If you want to advance/retard timing, turn the crank an angle amount equal to what you want, or place a timing tape and use a timing light. The timing of an engine comes from the angle of the crankshaft that the spark plug fires before/after. Thanks!

Why does the timing of fuel ignition change?
In order to have the same result, the fuel must be ignited much sooner in the compression stroke. As a result, the timing moves to 32 degrees before top dead center which allows the fuel to be ignited early enough so that it is burning while the piston is rising and completely burnt when the piston reaches top dead center.
