Checked the boots, everything was tight...took the plugs out they looked fine...what else should i check? How can i test for spark its kinda tight in there...and the leaking fuel? If is not burning is it normal for it to spit it trough the header??

Don't trust the look of a plug, just replace it , or at least swap it and see if the problem moves to the other cyl

Ok joel listen up bud place the plug up against the engine grounding it turn the engine over to see if the plug gives a spark. If it does not give you a spark pull the cap off one of the good plugs and place it on the same plug grounding it to the frame and check for spark.
If it does not spark with either plug cap then the plug is bad. If it spark with one plug cap and not the other then either the coil is bad or the cap is bad or the ecu signal is not getting to the coil. Yes if the fuel is not burnt it will leak as you see it doing.
Listen to the Master he'll get you going in the right direction.

13.6 on a Gen 1 is lean ...Gen 1s like 13.1 to 12.9 on the track with ram air .. You should be using stock plugs also ..

if you melted any piston ..you can catch it early and keep from having too much damage.. my eyes are bad but it sure looks like some aluminum flake on those plugs ..

correct.. the more rpm you give it the more air it pumps up the vent ... thats bad .. those plugs ain't as bad as some i've seen ..where the whole grounding straps were melted off and the pistons were fine but pitted .. but the metal from the grounding strap got behind the exhaust valves and pounded the seats .. thus failing a leak down test .. whenever i find something like your issue i do a leakdown ..the sooner you catch the problem the cheaper the repair most of the time ..
