Please help

I have a 1986 non turbo Toyota supra. basically i changed the engine and it wont start for me. i tried everything. its leaking power steering fluid and when i do start it, it won't idle. I have to rev it to make it idle. When it trys to idle by it self it will just die. I looked at the timing in the distributor and it doesn't look like its missing time. My previous engine had over heating problems. I need some opinions please.

Thanks!
