Run fault codes and check for injector tip problems and injector wiring problems --low fuel pressure and coil/plug leads problems . Possible moisture in the HT side of things.

1997 Buick LaSabre 3.8 engine.

About the only thing that would make all 6 cylinders flood out is the fuel pressure regulator or a computer problem. You say you have checked the regulator, so the next step would be to check the injectors for a short to ground.

Changed spark plugs in 97 buick lasabre and now it cranks and runs, but white smoke coming out. Is that blown head gaskets? Does it have anything to do with the fuel pump my mechanic put on 3 weeks ago???

You need to check the oil with the dipstick (wipe in down a few times) to see if it looks like a chockalate milk shake. If coolent has made its way into the oil you have blown head gasket. The fuel pump which is usually in the gas tank in most gm vehicles would not cause white smoke, if it failed you car would not start because your engine would not get any gas to the injectors

1999 buick lasabre hesitation while driving.

there are really only 2 things that cause this problem most of the time i have seen it, 1st a defective Mass Airflow Sensor, the second is low fuel pressure from a failing pump or obstructed fuel filter do u have a check/service engine soon light on at any time? have u had the system tested for trouble code's? Go to any Kragen or Autozone and ask for a OBD 2 trouble code test, it is free, record any code's that show and post them back here on this same thread.

1994 buick lasabre

Jack the car up. Remove the brake caliper and tie out of the way. Remove the outer tie rod end. Remove the upper ball joint. While the car is still on the ground, use a breaker bar and socket, loosen, and remove the axle nut. Remove bend the spindle assembly outward and push in on the axle to take it out of the hub assembly. Once it's cleared the hub assembly, give it a good tug and the axle will pop out of the transaxle.
