I've been running one of the cheap eBay "A Team" HEI distributors on my 250-powered lemons racer for like 8 races now.
Trying to get my new motor firing and I've got no spark.
In total I've tried 3 different units: the "Old" one, the "backup/spare", and a brand #$^*ing new one out of the box.
So far all Ohm out as they should and give me the ground pulse that they should when spun, but I get no spark once in the car. While these cheap HEIs are kinda notorious, the fact that one that was just running, and another is new out of the box has me thinking the problem's on the car side, but...

- The block is grounded to chassis with a ~6ga wire, ohms to nearly nothing
- Resistance from ground terminal of HEI coil to body is <1ohm
- I've got 12.7V into the unit w/ ignition on, but like 10V cranking
- I'm going to re-re-recheck the coil + 4-pin module + pickup because why not.
- I suspect the starter might be pulling too much current and it's turning slower than I'd like. I've read if it's spinning too slow it won't spark. So tonight I'm dropping in a new starter.
- If voltage is still low will run the HEI off a separate voltage source.
- Ground issues seem to be a common theme in mystery HEI situations, so will probably run a dedicated ground wire out of the unit to block ground.
- Set the whole thing on fire and walk away...
