Spark/ignition issues?

340mopar said

Just had this same thing with my sons '54 Dodge truck with a /6 and Mopar ignition. We started it up for the first time last saturday and it ran fine. When we went to start it Sunday morning, nothing, just intermitten firing of a few cylinders and would not take off. The plugs were nasty so we changed them out but still the same thing. I told my son to put a differnent box on it and it fired right up. I think your orange box is dead.

Hmmmm....will it really cause ignition to be intermittent? I figured it'd work right or it would fail completely. It has a ground wire, doesn't it? Or does it get ground just from being mounted to the car body? It should have ground, since it ran fine before, but I guess overtime that physical connection could get flaky.

My plugs are old but low miles on them, they look fine except for the black soot from the car running too rich (another reason why I'm trying to adjust the carb) and same with the wires but again little mileage. I have new wires to be put on but that can't be the case for complete failure of spark anyways.

BTW, when I did put the carb back on I DID forget to hook back up the PCV hose, but I remembered it after cranking the engine twice. After that I checked to make sure I had all my connections proper to rule out a fuel issue. Again no spark, so there's definitely a problem there.

Thanks for the replies everyone! I'll try looking at the orange box tonight. Is there a way to test this thing with just a dmm? Any specs on it?
