Ignition problems - Duraspark II

Having some troubles with my 351W, no spark.

Everything is wired up correctly, pretty damn sure it is.

Everything is new, coil, ignition module, distributor is a reman.

On the coil, i noticed a little bit of oil residue around the outer top piece, took the wire going to the distributor off and there is a little bit of oil sitting in the bottom, is this coil defective? Can I check it with a ohm meter? What should it read?

It is possible that the coil is bad.

I really like the square, dry coils like the newer EFI cars have over the older, round cylinder oil filled type. You might try one of those.

Can I use the TFI style coil on a Duraspark II ignition?

I found specs on what the coil should be reading and it's bang on within the specs, but no spark, it's all wired up correctly.

Headers arrive this week so I need spark so I can fire this thing

You can use a TFI coil with a GM module. I had problems with weak spark in mine so converted to TFI coil and GM module. I was able to drop down a jet size due to better spark. I'll have to search for the links on how to do it though.

Slap a MSD 6al or a crane. I am sure you spent your share of money putting together the 351. Why not buy a ignition system with a rev limiter to protect it. It's cheap insurance.

If it helps, there is 5v between the primary windings on the coil and jumps to 8v while cranking.

If the distributor is out 180* should it still spark?

Your voltages should be 8v ign "on" and 12v cranking, not measured between terminals on coil, but on "+" side of coil to ground.

Dist will still spark no matter how it is dropped in as long as it is turning.

Where are you checking to see if you have spark at??

Got in touch with the wiring kit manufacturer and everything was confirmed to be wired correctly, power was getting where it should, they said get another ignition module (even tho the one I have was brand new) plugged in the new one and voila it works!
