Hello, I'm working on a 2001 Silverado 4.3. I'm getting no spark from the coil. The coil is getting 12 volts on the positive side, but I'm getting no signal from the ignition module. The module is getting 12 volts at the supply terminal, good ground, and about 2-3 volts from the PCM when the engine is being cranked. The module is not sending a signal of any kind to the coil.
Does anyone know how much voltage I should be getting at the ignition module from the PCM?
Any other ideas of what I should be looking at???
Thanks
