Help...problem with inclines

Whenever I start my Integra ('94 RS) on even the slightest incline, it cuts off. By about the third try, it starts. The injectors have recently serviced, and the fuel filter has been replaced. What could be the problem?

fuel pump; maybe:eek7:

hmm sounds like a possible fuel pump does it matter which way the car is pointed(up or down hill??)
