Carry on
I think it's a safe assumption that people are overlooking the differences between different brands of headers and how far away they locate the O2's from the outside air. How far from the O2's is it to the atmosphere with your QTP HV merger collectors???

I believe HumpinSS is dead on with his assesment. Some people will be able to get away with open headers, but this is most certainly your problem. As for why your car won't start, you've probably fouled your plugs. Pull them out and I bet they are as black as night and filled with soot. If they are expensive unit, you can try cleaning them up and removing some of the carbon. Otherwise, get a new set and I bet it will fire up again. Just don't expect the new plugs to last much longer under the same conditions.

Good luck,
Mike

When he asked if it's cranking over, it can crank over without firing/starting. Can you tell if the crank is rotating when you turn the key? I am fairly unfamilier with SLP's......did you have to move/remove the starter to get them in? Plug change wouldn't be a bad idea.
I am just now ordering new plugs after I drove for weeks open header last year. It ran okay though.
