It runs great but will not fire up while I'm turning the starter, only when I let go of the key to the on position. Not a huge problem but sometimes I,m cranking the starter longer than necessary or not long enough if I've flooded it or something. unusual? a short? | | |

I have a wire that runs from the starter to the coil. It only feeds the coil when I step on the starter.
if it dosen't need fixed, break it

If this is correct, what is happening is the lead that used to go from starter solenoid to the coil to bypass the resister is actually supplying constant DC to your coil when the starter is turning. The coil will not produce a spark under these conditions. You can test this theory by removing the wire from the solenoid and trying it out. If I am right, this is not a good situation for your electronic ignition and it should be corrected. | | |

The resistor bypass wire is missing or not hooked up, and the coil is not receiving any voltage untill you release the key. Verify this with a voltmeter or test light. Key on engine off, coil should have 12 volts (positive side), now crank engine. Does coil have voltage while cranking? If not, run a wire from the R terminal on the starter to coil positive. | | |

What makes this situation different is I now have an coil internal to the HEI distributor and also lost the resister. I don't have the resistor wire on the starter any more and thought my new system was O.K. without it. I talked to the wire harness manufacturer and they will add that to my system. something perhaps related to my ignition switch-had to buy a new one, didn't have an original. Anyway, learn something every day and I have always appreciated hearing what you folks who know something have to say. These forums were great for this apprentice wrench fetcher! | | |
