did you check the fuse?
I get about 30 miles to the gallon with my olds achieva.
i have a 96 olds achieva and my high beam light was flashing, i checked the headlights and one of my low beam headlights was out. once replaced the flashing stopped.
The coolant level switch on a 95 Achieva has a sticking problem. If you tap the coolant tank near the sensor the light will go out
no you have to remove fuel tank
it broke
Check the brake fluid.
There is a diagram, for the power window system, for your 1995 Oldsmobile. The diagram can be obtained from most General Motors dealerships.
1-2-3-4-5-6
owners manual says 15 gallon.
Could be a failing fuel pump.
Should be in a removable housing at the engine end of the upper radiator hose
