My 92 previa has lost spark, I have battery voltage to + side of coil and 10.8v durring crank. I have put a test light to the - side of coil durring crank and it flashes lightly. The coil resistance values are right to spec .5ohms primary and 11k secondary. The coil wire has only 3k resistance in it. The distributor pick up coils are within resistance ranges and all of the wiring in the circuit has good continuity. And yes the distributor is spinning. I replaced the ignitor. Tested another ECM. Nothing... I am at a loss as where to go from here???? Can a coil with normal resistance and no visible signs of trouble be weak?
I tried holding the coil wire while the engine cranked and there is a weak spark, enough to hurt, but not enough to arc to ground.
ANY HELP PLEASE......
