My Uno cannot start and I went to a local repair.

My Uno cannot start and I went to a local repair man and he tells me that one of the fuel pump does not work. Surprisingly when I had gone to Bloemfontein and asked an agent he told me that Uno has only one fuel pump. What happens is it starts but after a few seconds just shuts down and wouldn't start again. I have bought a pump from Bloemfontein a year ago. Could it be that I should change the pump again or is it something else?I am a frustrated lady staying in Lesotho who has enjoyed driving this car but of late it frustrates me
