    Hey guys so I have a 98 z71 it's having problems starting runs great when it dose start it dose have a slight miss at idle though i already Replaced the fuel regulator and fuel filter I haven't gotten around to putting a gauge on it at all or testing the pump I'm just stumped here if the pump is going out it would have a miss and feel sluggish when you got on it wouldn't it? And it's been like this for a while now guy I bought it from said it did it to him the whole time he owned it I'm just stumped injectors ? Pump? Cap n rotor ? Lol

    I really appreciate any help thanks Chris

    Checked timing, plugs, wires, everything that makes sparky happen?
