Default honda civic ex 1998 swap not running right

I just finish swapping my obd1 gsr motor in my honda civic. The car will barley want to start and idle rough. I got the jumper harness and put the obd1 p72 ecu. I also cant gas it, if i try it just act like it gonna die. Like it way out of time. I got the car to run right twice. IDK what esle to do. Any advice would help. This motor came from my running 4drteg. Is it my TPS or Map sensor? and when i un-plug my map sensor isnt it suppost to die??
