I have a 90 Chevy Suburban with a 350 TBI. I have changed the coil, the
distributor, and the computer. I had the ignition module checked at
Auto Zone, they said it was good. I checked the pick up coil with an
ohmmeter and it is good. I have power reaching the coil, but when
holding a screwdriver in the coil wire next to a ground, I get nothing.
What else could it be?
