Erratic Fuel Gauge Operation on Oldsmobile Aurora

Problem Description and Possible Solution

It is common for the sending unit to read the fuel level incorrectly. This is due to a defective module. Our technicians recommend having the complete fuel pump and sending unit replaced because the module is currently not offered separately from the pump and sending unit.

erratic fuel gauge. most says full even when car I near empty.
When I turn the key on to start the car the gas gauge goes past full and stays there until the car is shut off
I plan on changing the pump and sending unit soon. The gauge usually is below full when I start driving, then always goes up to totally full regardless of the actual fuel level.
purchased vehicle from a neighbor that was unable to keep up with cars needs due to finances...i did however fix alot of little things that i am mechanicly and electricaly inclined but this fuel gauge is just everywhwere and he did mention of 3 times at dealership but to no more than a month the same issue would show up for he that the problem was becoming expensive and dealerships have lost there touch with us consumers..and we have lost faith in there abilities to correct issues no matter the weight of task...
Not fixed yet the gas gauge is incorrect and fluctuates up and down while driving so I don't know how much gas is in the tank
My gas gauge has recently stopped showing the correct fuel amount in the tank. I have not fixed it. I have taken this car in for other numerous problems, too many. Mechanic tells me that it could die at any time because of cracked block and other big problems. I haven't even had this for an entire year yet. I have to save more money for a different car. What a waste of hard earned money. I only hope it lasts longer.
When trying to start the car the key has to be held in the crank position for long periods of time before finally starting. Then once it starts it dies right after. The process was repeated over and over about 6 times before full ignition was to take place. I have ordered the fule pump and sending unit because the fule guage goes from full to empty as you drive or sit in the car for more thst 20 min.
Half gas level and below fuel gauge will move up & down often.
Solution has been to reset gas mileage upon fill-up and focus on gas usage on the on-board computer.
I had the issue of no turn over when cranking on the first try about every 20 stats if the car was on a hill. One day it just did not turn over for anything when I was going home from work. I had it towed to the dealer and needed a new fuel pump assembly. When I had asked them about the erratic fuel readings before I got an inconclusive answer. It took a new pump to fix this at 112000 miles.
