Your basic SBC, MSD Grid 77303, 77203 and 82613 coil. Ran perfect in October. Stored it. Set valves, primed the fuel. NO SPARK. Green light lit up on the MSD but zero spark. Any ideas where to start. Nobody shows them available from retail to warehouses. 49 runs is all it had in it I guess?
When cranking engine is the green led on Grid blinking Off / ON /Off / ON ? If no blinking then you are not getting a trigger input from crank trigger or distributor trigger.

I had a similar issue when I first put my car together. All new components. Couldnt get spark. Checked all the common stuff, crank trigger pick up, grounds, etc. I was stumped, took 7720 and 7730 out of my dragster and replaced the new boxes. Still no start. So now thinking i may have fried my dragster boxes i put them back in it and it fired right up. So I out new boxes back in the door car, called my dad over and when I went to show him it wouldn’t fire, it lit right off and has been trouble free since. I have no idea what happened, the only thing that keeps crossing my mind is I had my 16v battery charger hooked up and noticed the racepak said like 19.4v. Maybe it has some sort of internal safety for too much voltage? Who knows, but it works now and i never charge with the power on now.

That is almost exactly what happened to my deal as well. MarkeMark gave me some ideas, everything checked out like it should fire off but last night, nothing. This morning, 3 cups of coffee and I gave it another shot. BOOM, started perfect and ran great. Went through 3 heat cycles today and not one issue.
??? I almost getting too old to worry about it. Thanks Mark and it was NOT a MSD problem, I will chalk this one up to MOJO I guess ;-)
