I have a 00 jimmy 4.3L doesn't have spark to the plugs. We have spark from the coil but from the distributor to the spark plug there is no spark. Fuel pressure is good so whats the deal? Also cylinder #2 have 0 compression.. but that doesn't cause no spark will it?

Do you have no spark to all cylinders or only #2 plug? Do you have zero compression on any other cylinders? What is the compression on #4 cylinder?
