I'm working through starting my freshly rebuilt 2056. It has the original D-Jet and is a 1975 motor. At first I had no fuel pump, I fixed that.
Now there is no spark from the coil. I traced the lead from #8 on the fuse box to the relay board then out the relay board. I have 12.4v at the coil positive but no spark. I'm testing it with a light-type tester. No bueno.... It is a Bosch coil, i believe it is a "blue" coil. I read here that there should be 1.5 ohms resistance between the two poles on the coil with everything dissconnected. This one tests at 7.4 ohms. A spare coil I had had similar results with no spark at crank and 4.6 ohms resistance. I assume i need a new coil...... Right? |

If you don't want to muck with the key on/off a zillion times, you can jumper the fuel pump relay. Just bridge terminals 30 and 87; the pump will run even with the key off.
