Bad grounds at one or more components would not create a total lack of voltage at the coil. Nor would bad grounds cause the battery to run down or give you a rash. Try to stay focused, even against the onslaught of well-intentioned but irrelevant hand-waving.
You must do some tests, and some wire tracing. Once you have determined which is the coli IGN wire, (using my instructions in another post) you need to do a few things. Trace it to its source. Is it the IGN switch or is it a circuit breaker?
When you have the "no voltage" problem, can you temporarily run a test lead from BAT to the coil IGN terminal? (Use the + battery terminal if the truck is a negative ground truck, and vice versa).
Will the truck start when you do that?
Let us know.
