Today I attempted to hook up a 12volt wire to my HEI. I ran a 12 gauge wire to the fuse box hooked the wire to the middle lower accessory switched plug that says IGN beside it. I checked the plug to make sure that the wire is switched on with ignition. Now that I think about it the marking must be for the fuse!? I then attempted to start the car. First crank engine turns over, car been sitting so maybe no gas in carb, I then pump the gas and crank it. Now sounds like no spark, then big puff of smoke from under the hood! Bad day already (see members helping members "97 Yukon help"), just put the yellow wire back the batt connector on the HEI, drove to get some gas and came in the house.

Could I have did any damage? Why did the car not start?

Thanks
