Answer
Hi Robert,
The fact that you get spark out of one of the coils (2 and 5) means that the sensors are probably ok as well as I would believe that the items you replaced are ok. Have you check the wiring continuity for the other two coils in the pack? The red/yellow at the pack goes to pin 18 at the controller, dark blue/yellow to pin 17, and the black/gray goes to pin 19. They all should be being grounded momentarily once per revolution, which you could check out by turning the engine over by hand with a breaker bar/socket on the crank pulley bolt and the ignition in the run position. You could check that at the coil pack plug. If you only see that on the 2/5 wire, then I would wonder about the flex plate which the sensor is looking at to be possibly damaged. Did you install the crank sensor with a paper spacer and press the tip agains the plate? If not, get a new spacer and try that again. Could the plate be wobbling so much as to move too far from the tip of the sensor?
Those are my thoughts.
Roland
