no spark
well, as the title states, I have figured out that my truck is getting no spark. I was just wondering if there is anything besides a bad coil that could cause this, and how I can check for it, I searched for threads but got nothing useful, any help is apreiciated...

Have you checked to see if gettin a spark out of coil? if its sparkin of the coil then i would check distributor, Plug Wires, Plugs. if no spark from coil could be CPS. im sure there is other stuff i not said but im not the best as far as ignition stuff goes

the most common problem is the crank position sensor. but it could also be a pick up coil or bad ecm if no spark from coil. the easiest way I know of checking the coil is to use a test light and the + wire on the coil should have constant power and the - side, the test light should blink when turning the engine over. if it blinks, then the coil is bad...if it doesnt, then the problem will be something else. I think some part stores can check the crank sensor and pick up coil. the crank sensor aint too bad to replace, but I have never replaced a pick up coil yet......
