my 1990 Chevy 350 has no spark I've changed everything I can think of checked everything I can think of any ideas
When you crank it over do the injectors spray. If not it will be the ICM (ignition control module) or the pick-up coil. Both are in the distributor. If you have fuel it may be harder to diagnose. The ICM is easy to change and you may have done it already but the pick-up coil is a little harder, the dist must be pulled from the motor and partially disassembled.
