1994 buick regal 3.8l v6 won't start sometime start

At the cold start it starts but then immediately dies down then won'tstart at all when i turn the ingnition key and attempt to start it justcranks but does not start, after turning the key to off position istill hear some humming sound for a little while from the back of thecar near the trunk and fuel tank. I am assuming it could be the fuelpump sound. i have half a tank of gas so it should still pump. Whatelse could be. A month a go I had the throttle positioning censorchanged becuase of an engine code (twice this year) but I do not getthe engine light any more.
What else could be the problem ? Please help

Could be a weak fuel pump or mostly plugged fuel filter check at the engines fuel rail for fuel pressure after you start it and it dies...if no pressure or low pressure, start with the filter,its cheaper.the humming is your fuel pump and that is normal.

When my 94 Regal GS frequently wouldn't start for 30 minutes to an hour after being driven, it was the crankshaft positioning sensor that needed to be replaced. I also replaced the harmonic balance pulley. The car ran more smoothly and started everytime.

I have a 1999 buick regal ls dying.


I have a 99 Buick Regal and it too dies out, but only when I use my turn signals. Sometimes, when trying to start the car...the dash lights would flicker and you can hear some sort of electrical ticking sound. As of today, my car will not start (5/24/09) it hadn't turned over since yesterday. After a process of elimination and searching the net, I think I need a new ignition switch. You may need one as well.
