also an easy way to see if you're getting spark is to grab an old spark plug, pull the plug boot off of one of the cylinders, and put the old spark plug in the boot. lay this on the valve cover, making sure the plug is grounded/touching against some metal. Have friend try to crank the engine. if you see the plug spark at the electrode, you're getting spark to the cylinders. if not, start with the distributor, and start doing some testing
