car wont run

What is your question?

i have a 1991 acura integra i was driving it the other day and all of the sudden i heard a click and then the car started to die. i checked the fuses and all of that when i pull one out it will start back up and then immediatly shut back off... the fuel pump kickes on but not like it did but its good (got a new one). it will keep power in the main relay but after it purges the lines it looses all power to the relay and wont start but still cranks.. i need some help with this one lol..
