I have a 73 240Z which I converted a few years back from points to a Crane 700 electronic ignition. Ever since I did the conversion I have had difficulty starting the car when it is cold and the engine easily floods. The spark appears weak while cranking and often needs a shot of starter fluid to turn over. The real problem is that it generally only starts after I stop cranking the starter. As soon as I let off the key to stop the starter from cranking is when it generally starts. It seems like the starter is drawing too much current but I'm fairly convinced that it has something to do with how I have the electronic ignition wired as this was never a problem before the conversion. The problem doesn't get better if trying to jump start from a running vehicle. Any suggestions?
