I have a 84 380 SL with 165,000 miles that has been well maintained and garage kept. I'm having trouble getting it started. It is not getting any spark at the plugs or the coil wire at the distributor. I check the coil wire for resistance was okay, checked the coil, primary and secondary wiring are good. I now am suspecting the Ignition control unit.

Does anyone know if there is a wat to test the ICU?

Thanks
