Car was fine, starting fine etc etc. Some minor starter kick backs here and there. Then one day it stopped firing. Starter turns over and that's it. So I thought the MSD box went bad. And it begins...
So now was a good time to swap it out to the 6al-2 programmable and an MSD 85551 distributor and rewire it all. Nothing...
So I thought maybe the box was bad out of the box, so I tried another one, same thing. The thing I did notice was when I pull the pick up harness off the distributor the LED on the box would light up (it should be lit , when switch 12v is applied). Plug in the pickup harness it would go out.
Long story short after trying three coils, two 6530 boxes, wiring it straight to the battery , changing the switched 12v wire over and over again, checking TDC setup and everything else under the sun, it still wont spark.
Changed the plugs, switched back to a basic ready to run distributor (brand new one too) and I still cant get it to fire.
OK so what stupid thing am I missing here? I even went so far as to put a new battery in it (desperate!!).
Previously running I had a digital e-curve distributor with a 6421 box and that was running great for about a year or so.
What in the world would stop this from firing!! New everything all new wires, direct to fusebox and battery, theres no excuse. I don't get it.
Engine is a 540 bbc, t-56 trans, starter is new, alternator is new. Everything is new within a year or two.
