Truck wont start

its a 351M in a 77 f-150. It ran before, even on the gas that was a few years old. Recently I had to move it out ofthe shop and I had it running and then when I stepped on the gas it coughed and died. I triedto start it agan but it wouldnt go, so I figured it was out of gass, so I got some new gas, it started once but did the same thing when I stepped on the gas. could it be the fuel pump? cuz to start ityou always had to pump the gas alot before starting

Could be the pump. I would change the filter first. It could be clogged. Does it have good spark to the plugs?

Try taking the air cleaner off and looking down the carb. Move the linkage and see if gas squirts. You might need to rebuild the carb. Take the top off the carb if it doesn't squirt out and see if the bowl has gas in it. Do you have any vacuum leaks? Does the choke work? Gas goes bad pretty quick. Use Sta-Bil if it is going to sit.

the spark should be good I just changed the plugs. the carb could be dirty from running that haggard gas through it..i'll havea look at it.

I poured soem gas down the carb and it would fire and stay running as long as I had my foot on the gas..but once I let off it would crap out and die..abnd wouldnt start back up unless I poured more down the carb. on time it did fire on its own but I had to have the gas pedal in liek the right place for it to start firing and start up..around half throttle...im thinking fuel filster first off..but if that doesnt cure it then I dont know?
