It Will Not Run!?!?!

[93POS]

Ok i have a honda accord, it had two valves break, so i replaced the head and rings while i was in there. ok reassembled and stuff, the car wont run, it fires but wont just start. Now i have great spark, timing seems to be impecable and i can smell fuel. Heres the weird part, i'm pretty good with cars....soo i pulled the injector harness to see if it was flooded and burn the gas out, the car started and ran for 7 seconds. i reconnect the injector wires and it wont start, pull them off and she starts perfect, no ses unless they are disconnected. I am confused. My thoughts... ground problem...injector pulse module or w/e messed up. any and all input is appreciated.
car is a 93 honda accord 2.2 single cam manual trans. color is green condition is pizzia delivery mobile

thanks G
