Coil Wire - I don't this is supposed to look like this.

I have had a couple of occasions where my little gem wouldn't start. I could bump the top of the coil and it would start.

I decided to go out today and get this corrected. This is what I found. It appears that the coil wire connector has corroded itself into the coil. Now I have the task of removing the wire contact and getting it all cleaned up and a new wire fashioned.

I'm not sure why I didn't use the new coil wire when I replaced all the spark plug wires. I'm hoping its still around. I'm surprised this one got by me when I was doing the various bit maintenance when I first bought her.

The main this is I'm getting her fixed now before she strands me some where.

It was pretty well frozen in there. I broke off the end trying to get it out. <damn>Then in an effort of getting the piece out of the coil I cracked the top of the coil.</damn>

I really didn't need this right now. but this will get the car back to being reliable.

I'd outright replace at that point. New Bosch coils are about $60 if I recall correctly.

And don't forget the new cable

Avoid the URO green wire if you can, they have a known problem with intermittent connections at the dizzy.

Nobody gets out of this life alive.

When did the infamous green wire enter into the OP's problem? Coil and coil cable/wire are the only things I see.

I've ordered a new Bosch coil and coil wire ends. I picked up a piece of solid core spark plug wire from my local part store this morning to make a new coil wire with. ($2 and change)

I have found with my Chevrolets that dispensing with the resistor wire on the coil wire and going with solid core increased the performance and made for a smoother running engine.

This is exactly what dielectric compound will prevent. Put it on all the dizzy connects and in the plug boots.
