Changing a fuel pump in a 87 chevy 1/2 ton P/U Step Side?

Has anyone changed afuel pump in an 87 Chevy 1/2 ton P/U,Truck ran fine for about 4 mnths then went to start it and all it would do is turn over,as soon as I put fuel down the carb it would start but then would die when fuel was exhausted.Any Sugs?|||fuel filter would be a better place to start.... could be a bad hose pumps going bad is rare but it does happen .... take off a line and try cranking after you change the filter.. should shoot a good spray its ok|||I recently changed the fuel pump on my 1500 1/2 ton Chevy pick up. Its no fun. Make sure you have all the fuel out. Then its take the mounting straps and the electric and the hoses off. The biggest problem you%26#039;ll have is the amount of fuel left. I would suggest getting a book so you won%26#039;t screw up so badly or get something out of order. Its not hard just bulky. When you get the tank off, get a brass drift and unloosen the top. Don%26#039;t use steel, it might spark and explode. Make sure all the dirt and stuff is off the hole where you unscrew it on top. Take your time.|||You could also remove the bed of the truck if you have the help to remove the bed. Usually four to six bolts hold the bed on and then it weighs a hundred or two pounds 2 - 3 people could probably remove it.
