[Bow Tie 67]

There has been a lot posted at pro touring.com about it and it is a mystery as to how just changing the long block would make it change and give it a code that shuts the ecu down.

The engine now has angle plug heads and the plug wires are in a bit differnent positions. They are Taylor thundervolt wires and are as goos new. The rotor for some reason has gotten as loose as a goose and can move back and forth the distance of the terminal in the cap and it can also rock up and down on the axis of the post of the distributor.

I am getting a new rotor tomorrow and hope to see it be the problem with it dying . The next step is to reroute the wires and get a couple of new ones to make them all the right length they need to be again. The thought is it may be the plug wires causing the over amperage going back to the ecu.

Accel says that the code 66 is caused by a bad coil or 6A box and to replace them both. I did replace them and it did not stop the code 66 from happening. The engine would sometimes run for 20 minutes and sometimes only for a few seconds but it always tries to start up and run.

This has been kicking my butt for a week now.

Any thoughts are welcome and if you have had any experience with the code or similar problem with an Accel system let me know.

It has to be something simple and what it is has to show up sooner or later.

With all the problem you have had Greg do you have any thoughts?

Thanks for any help you can give.

Jim the only thing I can think of that would have changed would be disturbing a ground. Go double check all your grounds for good connections. ie: remove paint at attach point, some gold anti-seize will help the electrical connection at the threads. I did not read other posts hope this is not repeated information.

Make sure your battery is still up to snuff also, again check its ground and positive connections, not to mention the charging circuit. More resistance should lower current draw, but who knows exactly what the ignition system is seeing.
