Setup:: SR20 redtop, Enjuku turbo kit, HKS 264 cams, Secret Services tuned rom, S-AFC, Z32 MAF, Greddy intake mani, FMIC, 740cc injectors, DP and N1.

Problem:: engine floods after shut down. It will start on initial startup in the morning, but after it's warmed up and the engine is shut down again it will flood all cylinders. Plugs are wet in all 4 and you can smell the raw fuel. It will not start again until you pull the fuel pump fuse. Once running it idles fine, drives perfect and has no problems whatsoever. AFR's at WOT are dead on. Idles in the 14's and runs plain stellar. Fuel pressure is set to 50psi static. SS tuned the rom for that fuel pressure and the 740's. I checked the injectors for leaks, and there are none. All vacuum hoses are attached and zip tied off. I willl check the ECU for a damaged case, and see if that has something to do with it.

I read a similar problem, but no one ever gave a solution.

Hhahah... it's ALWAYS the stupiest CRAP you never think of.

Mine was soooo obvious but I just kept looking elsewhere cause it all runs through your head at once. You always think the worse.
