We have a 98 Chevy with a vortex v6 motor. It ran fine yesterday and wont start today. We have replaced the fuel pump, coil pack, checked all fuses, fuel filter, new pass lock mod, new plugs and wires, had comp flashed, new distrib. And yet nothing. It will turn over just does not have any power. Help if anyone can.

Thanks!!

 

It's a Vortec, sorry pet peeve. Try spraying starting fluid through the intake, if it fires, its a fuel prob, if not its a spark prob. And go from there.
