How do you remove-install a fuel pump in a 1991 Chevrolet Lumina Euro?

That has a 3.1L DOHC, right? Either way, to the best of my knowledge all Luminas has a fuel pump in the tank. Remove the tank from the car, then remove the lock ring to get the "tank unit" or "fuel pump assy" out of the tank.
If you got a complete unit, you'll know what to do from there. If you got a (PITA) basic pump kit, you'll have a folded up sheet of paper in the same box with detailed instructions (possibly in multiple languages) explaining what to do, but above all be patient.
Also, remember that you should have no fire or electrical equipment near gasoline vapors, so don't use them when doing this job. Also, work in a ventilated area as concentrated fuel vapors indoors can affect you thinking and cause feinting or death.
After replacing the fuel pump, you may need to crank the engine for longer than normal for it to start the first time. It is a good idea to replace the fuel filter any time you replace the pump.
While you have the pump out of the tank, use a very low voltage (no more than two 1.5V batteries) to look inside the tank. If there's and sediment or debris in there, clean it out.

If it is an automatic transmission it is most often the torque converter that will cause the jerking motion of the car.. another way to tell is the car will start to die when you come to a stop.AnswerI had the same problem in my 93 lumina euro... it's most likely the fuel pump. AnswerMy 92 Chevy lumina did the exact same thing, it turned out to be my crank sensor, and crack sensor wiring.
