I have a 2004 Metropolitan. Last year the headlight went out. The bulb was good but no power to the bulb. Everything else was good, engine cranked dash lights and turn signals also good. I did a little research and found it could be the ECU. I have been starting it regularly over the winter with no problems. It started an ran fine until a couple of days ago. Now it cranks but will not start. Sound like there is no spark. Could this also be the ECU?
