The plugs would foul (excess fuel) and then nothing. When this occurred, they wouldn't clear with additional cranking. If I removed the plugs, sprayed them with carb cleaner, blew them off and reinstalled them, I could get it to fire. The coil fuses would blow when first starting to crank the engine. Larger fuse was required and they haven't blown since (amps drop way down once initial cranking in past). Tracy has mentioned that the coils can draw larger current when first cranking, so this seemed logical. Now that I have my starting technique refined, and a few other glitches corrected, it starts the same each and every time. My COLD starting technique is as follows (our mileage may vary)... EC-2 A-B Switch - A Coils - ON Injectors - ON Cold Start - ON Mixture - RICH Throttle - CRACKED SLIGHTLY Main Fuel Pump - ON Main Battery Contactor (Powers Up the EC-2 & EM-2) - ON Engage Starter As soon as engine fires I start leaning using the EC-2 Mixture adjustment knob. After 30 secs or so, I simultaneously switch off Cold Start and go full rich with mixture knob. I then start leaning again with mixutre knob, maintaining smoothness. Hope this helps, Mark S. Hope this helps. Mark S. Quoting Steve Brooks : > John, > Are you getting spark ? If the plugs are wet at all, you should get some > fire out of it.
