I have a 91 Grand Prix GTP with the 3.4L and was driving it the other day and got on the gas a little and then it just died! The motor cranks over but doesn't start the tach doesn't go up when you crank it like it should either! The spark plugs do have spark and I went ahead and replaced the Crank Shaft Sensor and it didn't help. Also, I replaced the fuel pump, ignition module, and coils, plugs and wires, alternator and battery a few months before! If anyone has any ideas on what could be wrong it would be greatly appreciated! Thanks

Spray some starting fluid into intake to rule out fuel.

Start checking fuses and fuseable links, it sounds like you have changed most ignition components.
