Problem with fuel pump or injectors 1993 GMC Jimmy slt 4X4?

[Alex]

two days ago my Jimmy died at a stoplight and wouldn't start. it wasn't getting any fuel. with help we manually put some fuel into the engine and it started up fine, then died out. Towed it back to my house then today it started up fine with no problems. could it have just been a clog??

sounds like a fuel pump goin out check fuel filter. if ok you probably need a new pump. one test i do is bang on the bottom of tank and usually will come on but thats not a fix. that means the brushes in the pump are wore out.
