Sounds like dirty gas and the fuel filter is clogged...try changing the fuel filter...some are under the car, but most are mounted against the firewall in the engine compartment.
SOURCE: where is the fuel pressure regulater on a 1998 chevy astro van ?
it is on the fuel rail on the engine its next to the fuel line conection from tank to fuel rail for injectors
SOURCE: how do you change a fuel pump on 2003 chevy astro
on the engine compartment on the fuel rail there is a pressure port that is usually covered by colored plastic cover open it then turn the ignition switch listen for the sound of your fuel pump turning on momentarilly. if you cannot hear it while ignition is on insert small screw driver on the port to open the valve make sure you wrap rugs to control the flow of fuel if there is any. the fuel should around 40-50 psi so expect heavy fuel coming out at port if your pump is working. to change it you have to drop your fuel tank and replace your pump. this is usually left for professional due to fire hazard. any spark due to static electricity can set your fuel to flame up.
