How much can those iridium plugs take flooding?

Iv made singleturbo conversion and have 550cc primaries still in to get the car going but i have problems getting it started. I had it going for a while when i made the PFC-diagnostics run but it stalled after that and i havent got it running after that.
Ill change battery the first cuz i think mine went bad during winter and second idea is plugs. Any ideas? Mods include ratnest elimination, 1200cc secondaries, fpr, pfc and some plock off plates.

And second broblem is electrical. Some of my electronics were acting up when i first got the car and one of them is that my speedogauge lights dont work but the small screen that has mileage in it has power, but when i turn lights on it dies and glovebox light up
