Keep in mind that WOT also shuts off the fuel injectors and is also known as "Clear flood" mode, which is I am curious how the spark plugs look. If they show signs of being fouled already (since they are new) or are wet with fuel, that could suggest either too much fuel or the fuel that is getting to them doesn't want to burn.

But your comment about air flow got me wondering if there's a chance you have a restricted exhaust (more common than restricted intake) which might help explain the no start as well. to check for an exhaust restriction, one thing you could try is to remove both pre-converter oxygen sensors. The small holes from the sensors won't be enough to support full throttle if the exhaust is plugged, but they should allow enough exhaust to escape for the engine to start in such a scenario. And if the intake is plugged you could identify that as well as a lack of air coming out the holes when the starter is spinning the engine over. I guess a compression test would help identify that as well though too.

Hmm, maybe the compression test would be the easier place to start.... Or if you happen to have access to a cylinder leakdown tester you could test both scenarios just by removing the spark plugs, installing the leakdown tester, and slowly turning the engine over by hand and listening for where the air escapes (throttle body when intake valves are open, tail pipe when exhaust valves are open).

pulled plug #5. Shiny clean still just a tiny bit of black at the spark point.

Smelled a touch of gas on the plug.

have to go get the adapter for the compression test

 

well, this sucks. Started testing the compression 1 = 120 4 = 0 (not even a wiggle on the needle) 5 =0 (same things)
Plug one fouled.

looks like its new heads for me.

 

That does suck. Absolutely no hint of compression sounds a bit suspicious too though, but short of using a leakdown tester to determine where that compression is going, I'm not sure what more to suggest you try.

i was thinking that was suspicious myself. i almost thought about taking that gauge back thinking it was broke
