MSD6AL box go bad on a twin plug setup?

[Geneman]

Well Friends . yes I am an idiot. Thank you for all the help. Turns out There is a huge blockage in the fuel pickup . inside the kevlar box of the fuel cell. i thoroughly cleaned kevlar lining , installed new foam, and also thoroughly vaccuumed, i thought, inside the fuel slosh box. you cannot see in there, alll you can do is feel. and i thought the intake was fine. turns out the plug . which seems to be MOUSE FUR!! was stuck way in there. so it might have sloshed out over time, allowing some fuel past, then rejammed up on track in first few laps.... at least i now have two extra coils, two MSD boxes spare, another rotor and cap....

David Murry told me this is the laboratory mouses cousins getting revenge! as i do molecular genetic studies on mice with cancer.... and tend to off alot of them...

Ah, that’ll do it! Glad to hear you found it. Might want to check the pump and filter to make sure no crap got through and caused downstream clogs. When’s the next outing?

Have fun and be safe at VIR.

Again, after 20 years around similar equipment (my own and quite a few friends) have never seen a situation like this that turned out to be an MSD box. I have had two coil failures, and one was my fault.

I still carry a spare box and a couple of spare Blaster coils, just in case.

When dealing with things like this, systematic troubleshooting is obviously very helpful.

I have a friend who is a racer and retired BMW master tech. He says... "the car never wins." But of course we all know they can sometimes put up a pretty good fight.
