when you do get it going when cold, does it idle up over 1k? or does it stay low, around 600?

if it doesn't get over 1k then i'd be looking for a cold start valve blockage. that being said, i dont even know if the 1uzfe uses a cold start or if its done through the throttle butterfly. if so, clean your throttle body.

another thing to try, is turn the key to acc for a little while, and let the fuel pump prime - you'll hear it whirr, then stop. then turn the key. also try a little throttle opening to try 'catch' it when u turn the key - but that's not a solution to whatever is causing the problem just a way around it.

the fact that it's starting fine when warm makes me think firstly cold start system....could be sticking shut. but the fact that its starting second time every time when cold, makes me think fuel. investigate and put findings up for others.
