help!! 84 gt HO not starting..?

last night my 84 Gt HO automatic shut off while driving in traffic and it didn't start back up it showed check oil when i tried to start it i hadn't seen that light work before... towed it home ..if i spray gas into intake it will start for a little bit and no fuel coming from lines...i tryed pressing the fuel reset in the driver side of the trunk and nothing also oil level was good and a i added a little more and still nothing what could it be ? where is the fuel pump relay? is it electrical pump? where is the pump located? any other fuses to check? also a week before the ac stoped workin and somethimes i had to give it gas for the car to start not all the time ?? help will be appreciated need it for work

i dropped the tank and magicaly the pump started working again so put it back together 2 hours later the car turns of again... could it be the pump going bad? where is the fuel pump relay?

i forgot to mention i replaced the fuel filter and it has a electric pump in the tank when i dropped it i tested it with a tank of gas with the same conetection of the car and it would pump small amount gas then i tried it later and it pumped out a lot wich seemed right and i decided to put it back ...could it just be the pump? or is there a chance its the power going to the pump? and right now the pump wont even prime...the inertia switch if i press it all it does is come back up is that right?

i replaced fuel pump and its working now ... had a bad fuel pump that quit whenever it wanted to
