A spark plug will fire in open air much easier than it will under compression. Try what already has been stated, run a temporary wire from the battery + to the + side of the coil. Don't leave it on too long or you will cook the points.

Ok, I got it started again but would not believe it if someone else told me what I did. I moved the distributor clockwise by at least an inch and it started but was running poorly to say the least. I then moved the distributor back to the original position and it starts and runs like it did before all this started.

Thanks to ALL for the suggestions and if anyone has any idea how this might have happened, feel free to post your thoughts.

Look closely at the black wire from the points that then leaves the distributor.

>>. I then moved the distributor back to the original position and it starts and runs like it did before all this started.<<

This is where you get a timing light and set the timing, but wait, before you do that you need to check the dwell, because that is probably the reason it wouldn't start in the first place.
When points get old, dwell changes and that changes the timing.


>>Checked coil positive to ground and got 5.29 V<<

This is the voltage you will get when the points are closed and shorting the coil voltage to ground.
That 5.29V reading is of little importance other than that it is there. With the engine running, the points are closed for only milliseconds at a time, depending on engine rpm.



>>Checked coil negative to ground and got 0.24 V<<

.24V indicates point resistance. New points would have lower resistance and show a lower voltages. Old burnt, corroded points will have higher resistance and have a higher voltage indicated.

I second JJohnson's above post....even change it out would make me feel better..

Here is my theory as to what happened:

When you moved the distributor you really retarded the timing but the fix was that you moved the wire JJ mentioned and got full power to the engine but bad timing and running terrible continued...you then put it back in better timing and the wire that caused the problem that needs replacing did not mess up and stayed together....for now!!!!!!

We are talking about the wire that goes from the negative on the coil to the distributor.

I bought that wire at NAPA or O'Reilleys I think it was...I have the # downstairs in a box somewhere...if you cannot find it....PM me and I will get the number.

Points have less than 200 miles on them but nothing would surprise me. I agree with JJohnson that the black wire is probably the culprit and as suggested by Jimmy, will get replaced ASAP.

Thanks again for the help.

NAPA ECHLIN LW72, can't make it any easier than that.

Ya, except that at the time it wouldn't start, if the distributor wire was open or even if the points were open, you would measure battery voltage on both the coil Pos and Neg posts.

You indicated,
>>Checked coil positive to ground and got 5.29 V<<
>>Checked coil negative to ground and got 0.24 V<<

Thanks Richard. Definitely going to pull out the Tach/Dwell meter and go over everything again, one step at a time.

This doesn't explain the fact that he had spark at the plugs when it wouldn't start. Jerry

Can't disagree with that. The only thing that I'm sure of is that it only started after I moved the distributor an inch or more clockwise and worked fine when I move it back. I marked it before I moved it and verified with the timing light after putting it back in the original position. It makes no sense at all but replacing the wire is cheap and checking the dwell and timing again is free.

I wish I had a definitive reason for the failure but I think this one will a mystery to me.

If the wire was not completely broken but had a few strands still okay...it would not be producing enough juice to the condenser is my thinking....may be wrong but my money is on the wire is faulty...maybe Freeman will find the culprit when he changes out the wire....we will see.

I would put hook it up and move the wire around and watch the voltmeter for volts and ohms.
