Exclamation MSD no spark problem - all new components

Had a 6AL with a new 8252 HVC coil. Three years old, but new.

No factory wiring left, so no concerns there.

Heavy red and black directly to battery. No issue there.

12V wire comes directly from Painless switch panel that is powered direct from remote battery terminal. No issue there.

Orange and black to coil - yes, wired correctly.

Violet and green to MSD 85805 Pro Billet distributor.

No spark at coil when cranking so I tested the box using the jumper wire method with the coil wire to ground. Nothing.

Bought a new box - a Digital 6AL (nice, slimmer design). Wired the same way as the original, except this has a neat red indicator light.

Still no spark.

Ordered a new 8252 coil. Installed it same as the old. Nothing.

I'm at my wits' end and really want to fire this thing up. It's been a few years since I've started it as I've been building the rest of the car.

There's a prize for the winner.

I had about the same problem so I bypassed everything and no spark on a 6al that was fresh outta the box. I returned it and that fixed my problem. So u might have bought another bad box but before u return it try running ur remote wire directly to the battery also just for gp and see if that does it. Do u have ur pill for the limiter in? Usually it's something stupid.
