You could connect an inductive type timing light to any spark plug wire; and see if it is firing.
Probably your vehicle is not running; and your trying to determine 'why'?
A bunch of different sensors and components can be the reason. Get yourself a good manual (like Factory) with good info; and this will help you out a lot. They have flow charts and diagnostic trails to follow.
