Here are the facts:

89 CRX si - all factory OEM OBD0 electronics

While driving at a steady speed on the interstate, the car just shut down.
CEL = 8

I have replaced the ECU, distributor, wires, plugs, main relay, and ignition switch with known good units. Double and triple checked all fuses and breakers. All grounds look to be good. Went through Helm's manual diagnostics for determining all continuity and resistance values were correct for dizzy and ign switch. I have fuel pressure.

I have run out of ideas on what could be causing the car to have no spark :sad:

Anyone else have any possible ideas?
