I have a 98 Olds LSS (same as Bonneville SSEi) and am experiencing problems with starting. If the car sits for a period of time it will take a while to start. For example, if I leave the car over night, the car will crank over and over, then I let it set for a couple seconds and it will fire. If I drive the car for a couple minutes, turn off it off, it starts with ease.
It almost sounds like it'* take a while to build fuel pressure.
Any thoughts? Do you think its time for a new fuel pump or possible a fuel pressure regulator?
