My car loses power sometimes and I can have the pedal on the floor. What causes this? I have new spark plugs and wires, fresh air filter good engine oil life. (1999 pontiac grand prix 3.1 v6)
Could be many things but,i would put my money on a weak fuel pump.Check your fuel pressure it should be 41-47 psi with key on engine off.If its not within these specs replace pump and filter.

I already replaced the crankshaft sensor. When the car gets hot it won't crank and then when it cools down it will start back up 2000 Grand Prix 3.8
Could be ignition control module or fuel pump, if you don't have spark to spark plug's, control module, also check for fuel pressure at fuel pump pressure port, port will be on fuel rail.

No pressure at fuel rail on 88pontiac grand prix can not hear fuel pump kick on
Did you check your fuel pump relay and related fuses to make sure no fuses were blown? Passenger side under-hood electrical center shows # 3 fuse 20 amp fuse controlling fuel pump and ECM. Also #12 is also Fuel pump relay in Passenger side under-hood electrical center. These would be the first things to check.
