1985 Van - no spark

[James Adams]

I recently acquired a 1985 Toyota Van that will not start due to what appears to be no spark. After replacing the whole distributor with a remanufactured one (which includes a new ignition module, pickup coil, and ignition coil), the problem persists. The engine diagnostic code stored (6) indicates no ignition signal.

The resistances on the coils on both the old and reman distributors are all within spec. I also have 12V to the distributor power connector when the ignition switch is turned on. I tested the wire for spark plug #1 and there is continuity and the resistance is within spec. Even if my timing was off, I should still get a spark (with the spark plug body grounded via jumper cable), but I have no visible spark and it will not trigger a timing light. Any thoughts?
