car won't start Help!!!!

after finishing my dpfi to mpfi convert my car would not start, i check for spark and there was spark and the timming was right and then i went and check the fuel , the fuel did injected once every time i crank it with the pm6 ecu and only once so it starts then it die. but it would inject with my old pm5 ecu only 2 injectors were injecting , and i was wondering why isit not injecting repeadedly with my pm6 ecu.

I Check my wiring lots and lots of time tring to find the problem for about 2 weeks now and needing my car to be running .

any advice or a solution would help ...
sorry about my grammer and spelling.

thnx u
