To be continued.....I guess the test will be a decent highway drive of some reasonable distance with traffic....
Then, how is that you had no spark previously? Weird...

Well, I hope that fixed your problem

No spark? I remember the first time it did it a few seasons ago.....I was able to get it back to my garage.....Next day I go to start it, cranks but does not turn over..I tried it a few times, still no start..

A mechanic friend of mine came next day and pulled a distributor wire and determined, no spark.....Locked it up covered it and said- I'll mess with it later.....

Two days go by, I tried starting it and bamm, started right up.....

Yes, weird....

I'm hoping last repair is the last repair...

Could it be due to a boiling ignition coil ? Not unusual..

Took me a while to find this thread....Took the car out today , first time in 4 months, stored it properly..

Well I'm on a street waiting for AAA same problem....Cars running great, starts to sputter a bit, idle drops than shuts off....

Let it sit for a while....Won't start just won't start....Cranks fine....Won't start...

Fuel sock, fuel pump, fuel rod, cap rotor, plugs all new..... Carb checked gas tank cleaned out....Same F in problem...

I think your problem is ignition related. I suspect your coil has been failing for some time and is just not ready to die yet. I would get a new one if it were me. Good luck!!

Check the coil you may see it's bulging or leaking.
The scenario you describe is EXACTLY the same as what happened to me (although a '66).




Good luck- and let us know.

I will let everyone know...My ignition is HEI....Motor is a 75 block....On your 66 I'm guessing it was easy to spot since the coil is right on top of the motor...

I just got it home and parked it....When I get a chance I have a spark tester and will see if I'm getting spark...

Payed for fuel pump, fuel sock, fuel rod and the problem still happens....Its dangerous as well....This S#%t happens at highway speed and everything shuts off .....

HEI/Spark Module sounds bad. Look at your MSD6L.
