1994 Cadillac EL Dorado car sputtered and it idled very ugly

I was driving down the street and my car has been running good with no signs of problems then my  below 1000 rpm. I tried giving it gas but didn't help and now it won't even star. I can hear the fuel pump. Question (follow up):Thanks for the advice, first I changed the fuel filter and it was horrible it was dirty as it can be and I blew in the fuel filter and brown gas poured out so I replaced it with a new filter. I sprayed the carb cleaner in the housing and it cranked but it seem to just burn the carb cleaner then it would cut back off I did this many times and same thing it seems like its getting no gas do you think the fuel pump should be changed because the filter was bad. What do you suggest?
