hard starting bravada

[uummm]

my friend has a 93 bravada with the vortec motor and it usually doesnt start but when it does it sometimes stalls. i am thinkin about gettin the bravada from him but i dont know whats wrong with it and dont know if its worth it. we tried the map sensor, and that didnt work. any suggestions would be helpful. thanks, ryan
