Re: no spark
Sure! Its worth fixing. If you have decent compression, that means that the mechanical portion is ok and you don't need to tear down the engine. Reall y good compression on that engine would be someplace around 130-140 PSI. Lower would be ok as long as it is not too low say below 90-- and equal within 5- 10 PSI on all cylinders
Now, as for electrical, There are so mant places where it could go wrong, that youn really need to buy a Clymers manual. However, a few hints. Check all ground wires on the engine--bad grounds probably cause more problems than any other thing. Be doubly sure that the short black ground wire that connects the distributor to the block is in place and not broken. Without that ground, the grease in the distributor housing may insulate it and then the points will have no-where to ground and signal the CD box. That engine needs a fully charged battery to function--The battery charges the CD unit and the points are only a signaling device to tell the CD unit when to dump its power into the coil. So be sure that the battery connections both at the battery and inside the engine are tight and corrosion free. Be sure there is no corrosion on the blue wire going to the CD box. This is power in to the box--no power or poor power in, no power out, no spark. Be sure the blue wire on the switch is connected to the "I" terminal and the red wire is connected to the "B" terminal. Be sure you don't have a "man overboard" kill switch, and if you do have one, be sure the clip is in place. Check the plug wires--The plug connector on stock wires is a spiral wound wire of regular steel with a hook poked through the wire. It tends to rust and break off. Plain white wire from the CD box is signal for tach and does not need to be connected to anything. White with black trace is signal from distributor. It runs under the flywheel with the blue. Be sure they have not rubbed on the flywheel, greating a short. Last, check the coil for resistance and see if the box looks ok. You need special meters to check coil and box function. These parts are not available through your dealer, but can be found at the Chrysler Crew franz marine.
