Angry Help me please?

I thought that I was the only person on the planet that has this problem!!! My 1991 Toyota 3vz Will not start unless I feather the throttle until it fires and then reving the crap out of it in order to keep it running followed by it not wanting to idle. It almost seems like the engine is loading up with fuel and it is deffinately fuel burning rich on start up. After it all burns off, the truck runs totally perfect.

The truck will not pull any codes and I've taken it to two different mechanics to figure this out for me. After paying these guys to fugure out what might be going on, I've only found myself on more debt.

I've replaced; 6 injectors, Plugs, Wires, rotor, cap, fuel filter, fuel pressure regulator, cold start injector, Cleaned EFI and throttle body with carb cleaner, done two leakdown tests, fuel pressure checks out fine and now want to just push it off a cliff!

If anyone could please give me an idea of what is going on it would be much appreciated.

I've checked all vaccum lines. It is definately loading up with fuel upon start up.
